I have written a small set of xkb rules to enable the extra keys on thinkpad laptops (keysyms 233 and 234). The rules implement new keyboard model 'thinkpad'.
The files are available with a html README from http://hile.dyndns.org/xkb-thinkpad.tgz You can probably just run diff for the files under xkb directory, the changes are quite trivial. It would be great if these configs would end up being part of the packages and upstream. There might be problems with the rules and the fact these rules replace the pc101,pc102 and other 'model' parameters in XF86Config-4, works for me at least with finnish keyboard. I think my mapping of 'Prev/Next_Virtual_Screen' is good to not mix the keys with any other, possibly used keys, and most likely map nicely to the tasks most people would do with these keys now: I see no other use for these keys except virtual desktop switching and window moving. *hile*
