didn't work with Etch: unsupported sata, installer say "no HDD", and impossible to load sata modules from console.
works with Lenny and Sid, but:
-add "asus_acpi" and "coretemp" (for lm-sensor) in /etc/modules
-get webcam driver here http://syntekdriver.sourceforge.net/
-add user in some groups for full control of screen light and powersave (powerdev, kmem)
-install fglrx (radeon don't works with the X2300), and Madwifi with module-assistant.
when all is done, all works (didn't test Xpress port), but the laptop don't cut the power after shutdown (stay on "will now halt") with Lenny.
shutdown OK with Sid (cut power after shutdown)...
