Sorry, my previous post per e-mail ended up in the wrong place and empty.
Don't know why.
I too run Trisquel on a Lenovo ThinkPad (R61). Currently I live without
wireless. (Bluetooth works, however.) The only other thing that doesn't
work (at least not out of the box) is the fingerprint reader which didn't do
so under Ubuntu either. I know that some ThinkPad users have troubles with
the volume up / down / mute keys but mine work fine.
There is a wiki page about Lenovo's wireless diseases on ThinkWiki:
http://www.thinkwiki.org/wiki/Problem_with_unauthorized_MiniPCI_network_card
The page also documents a hack to get “unauthorized” cards working but
the steps involved are definitely beyond the scope of the average desktop
user and might destroy the hardware.
I suggest you boot a Trisquel live system to see what issues your machine
might have. This won't touch your current install. Also see my other post
about that:

Hope you'll like Trisquel!
