After spending my evening on it :-(  I managed to find the correct keys for 
the Omnibook XE3: 
(I could only reverse-engineer the previous hack I 've had for it)
Download and hack the 'console-tools' package (from sourceforge, project 
"lct") so that 'setkeycodes' does accept keycodes >127.

Vojtech, is 512 the upper bound for <keycode> at setkeycodes?

Using 2.6.2-rc1, issue:
setkeycodes e071 236
setkeycodes e072 237
setkeycodes e073 238
setkeycodes e074 239

 so that the upper (near the screen) row of "internet" buttons is assigned to 
the keys X expect to receive.
e071 etc. can be found using 'showkey -s'
I still don't get where 236 came from (so that I could help other kbds, as 
well).
