Anyway, now to install Gentoo Linux on it!
The first problem I encountered was the classic install cd "no bootable medium found":
Attempting to mount media:- /dev/sdaI used the minimal install cd, which booted but couldn't "find itself" (after booting the kernel, the cd tries to mount itself so it can use the files contained on it). I tried all-generic-ide, acpi=off, playing with AHCI vs ATA in the BIOS and various options to no avail. In the end, I copied the install cd to a usb key, and booted from the CD. The install found the usb key media and continued to run! Thanks to here for this solution!
No bootable medium found. Waiting for new devices...
Could not find CD to boot, something else needed!
Now I've finished installing the basic system and I have the machine booted and logged in. I'm currently compiling gnome! I'll provide more details here soon...
The system was mostly installed within a day. This is my success so far:
Processor frequency scaling works (2.6GHz, 2GHz, 1.6GHz, 1.2GHz and 800Mhz. Conservative scheduler works well)
LCD WUSXGA works (1920 x 1200 native resolution)
LCD backlight control mostly works (DPMS works, but I haven't got the lid to switch off the display yet)
Touchpad (synaptics driver) works
Hibernate to disk doesn't (resume properly yet!)
ACPI and power button works
Speakers / sound card works
LAN, WLAN works
MMC reader works
multimedia keys mostly works (Some issue with play, pause, etc buttons)
DVD burner untried (DVD / CD reader works)
VGA / DVI / TV out untried
I'll post more details again soon!
