I have an EeePC 1000H
Sabayon works fine with it, Don't use the EeePC boot option, all it does is give low resolution, the standard 3D boot option works fine. however, the installer is a bit to big, so you have to set the bottom panel to hide or you won't be able to click next etc..
You need wired net before you have installed the rt2680, don't forget USE="networkmanager"
The touchpad works, but at least I haven't found a way to turn off the tapping(I don't like tapping, if you do, this is no issuee) since the EeePC don't use standard synaptics but some other I forgot the name of at the time of typing(I'm on another computer right now)
