Ubuntu

For this one I wanted a minimal maintenance stuff for basic laptop operations so I chose the latest Ubuntu at the moment: Lucid Lynx.
Actually they have a version special for netbooks, installable from a USB stick, cool:

Ubuntu Netbook 10.04

The only thing is that I wanted to only replace the 2 NTFS partitions and keep the last 2 partitions for now.
First time I tried I used the partition tool from Ubuntu installer but if it succeeded completing the install, after reboot it appeared that the partition table didn't contain refs to the root partition, ouch! So the new partition table was never written to the disk.
I rebooted on a good old FCCU liveCD v12 and changed the partition table the way I wanted then I did again the Ubuntu install, this time without troubles.

Out-of-the-Box

Working:

Suspend-to-RAM
Suspend-to-Disk (hibernate)
Webcam
VGA output
Ethernet
Wi-Fi
Audio playback
CPU freq scaling 1/1.33/1.66GHz, ondemand
sdcard reader
Silverkey disable touchpad
Hotkeys: suspend, Wi-Fi on/off, disable touchpad, brightness up/down, volume off/up/down
My 3G USB key (Vodaphone K3565 = Huawei E160)

Not working?:

multi-touchpad. See below the paragraph about Touchpad
Hotkeys: backlight on/off (not clear, it worked at the beginning, anyway it's barely usable without any backlight...)
Hotkeys: hotkey display toggle, hotkey display resize, taskmanager, super-hybrid-engine. See below how to use them with eeepc-laptop & Jupiter

Not tested:

Bluetooth, seems supported
audio mic

Tuning with eeepc-laptop

This modules gives access to the eee hotkeys & eee Super Hybrid Engine for better powersafe control

Install driver

$ modinfo eeepc-laptop
filename:       /lib/modules/2.6.32-23-generic/kernel/drivers/platform/x86/eeepc-laptop.ko

parm:           hotplug_disabled:Disable hotplug for wireless device. If your laptop need that, please report to acpi4asus-user@lists.sourceforge.net. (bool)

sudo vi /etc/default/grub
=> GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
sudo update-grub
reboot

Now eeepc-laptop kernel module will be properly loaded

Display:

If you run X11, you should use xrandr instead.

Camera:

/sys/devices/platform/eeepc/camera:
1 = on
0 = off

SDCard reader:

/sys/devices/platform/eeepc/cardr:
1 = on
0 = off

CPU clock configuration:

/sys/devices/platform/eeepc/cpufv:
0 = Super Performance Mode
1 = High Performance Mode
2 = Power Saving Mode

Reading this file will show the raw hexadecimal value which is defined as follow:

| 8 bit | 8 bit |
    |       `---- Current mode
    `------------ Availables modes

For example, 0x301 means: mode 1 selected, 3 available modes.

Jupiter

Jupiter is taking care of multiple power saving settings including the eee SHE & GMA950 overclocking if you install also jupiter-support-eee
See http://www.webupd8.org/2010/06/jupiter-take-advantage-of-asus-super.html To install it, there are a few pre-requisite:

aptitude install libnotify-bin acpi

Get .deb packages jupiter & jupiter-support-eee from here & install them

It takes also care of the extra FN buttons (there is also packages eee-applet & eeepc-acpi-scripts or eeepc-control if you prefer not to use Jupiter)

Touchpad

aptitude install gpointing-device-settings

& enable circular scrolling (System / Pointing Devices)

For multi-touch I'm not sure how to proceed. Lucid Lynx doesn't use hal anymore.

Bugs

At reboot I sometimes encountered the following bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/572279

Firmware upgrade

It has v1102, since there were a couple of new versions:

1401 Update brightness table
1301 Improve Wifi performance
1301 Update EC firmware
1203 Fix there is no "safely remove hardware" icon in windows 7 when plug in SD card.

So let's try to install v1401

http://support.asus.com/download/download.aspx
- EEE family / EEE PC / 1005HA / Linux
- BIOS 1401
Unzip archive
Rename file 1005HA-ASUS-1401.ROM into 1005HA.ROM and move it to a USB stick (my 6Gb USB HD wasn't detected I had to use a real 1Gb USB Flash)
Reboot on the USB by pressing ALT-F2 while rebooting
Flash is done automatically
Remove USB stick & reboot
