Important Work-Around Fixes
This system is relatively well-behaved with the Ubuntu and Debian installs I have tried it with. I've been fortunate with the supplied wireless card having out-of-the-box support since Ubuntu 5.10 Hoary Hedgehog. However, your supplier may have provided a different brand of mini-PCI wireless card.
Ubuntu LiveCD's
The monitor outputs don't automatically choose the LVDS port to which the notebook screen is attached. Altering /etc/X11/xorg.conf to include the line in bold and restarting the X Server resolves this:
Section "Monitor"
Identifier "Generic Monitor"
Option "MonitorLayout" "LVDS, Auto"
Option "DPMS"EndSection
(It might be a good idea to manually alter the alter the 'Section "Screen"' -> 'Subsection "Display"' -> 'Modes' to include the screen's native 1280x800 resolution.)
ACPI
The supplied DSDT with BIOS version 2.70 has no flaky behaviour errors, and recompiling it with the Intel IAST Compiler showed no errors.
Untested
The 5-in-1 card reader and the Firewire port have not been tested, but show up cleanly in dmesg and lspci. The BlueTooth? parts of the wireless adapter also have not yet been used in anger.
