Hi lynx,
mue and I started working on the x121e (amd) which might be similiar to the x120e.
mue has atm all the hardware, just ask around, maybe you can continue the work together. Creating a wiki entry would be nice with lspci lsusb attached. I've also found the schematics for the x121e intel version. x121e is the name for two baords, one based on amd and one on intel.
just ask in the irc for mue or me.
best, lynxis
ps. nice nickname ;)
