Just installed sabayon core 5.1 on my eee. Everything seems to work fine apart from two minor problems, the first being that /boot/grub/menu.lst needed vga=788 appending to the kernel line.
The other issue is that i cant get either fn+f1 to suspend or fn+f2 to disable the wireless. Ive checked to make sure the eeepc_laptop is loaded, but beyond that I'm stumped.
Any ideas people?
wifi problem was i belive being caused by not unloading the ra2860sta module properly
suspend was fixed by installing the acpi scripts from http://code.google.com/p/acpi-eeepc-generic/
