Have the exact same problem with the Intel x3100 card. Was going to
try and work through it on the list this weekend. But I'm glad you
brought this up now.

The volume keys work fine for me in Ubuntu Gutsy & kernel 2.6.22 ...
even without the thinkpad-acpi module loaded. Just plain ACPI. Make
sure you compile the latestest HG build of ALSA that has proper
support support for the sound card in the T61.

This is actually for all thinkpads you have to unmute by pressing
Volume up or down.

Bothe work fine with Ubuntu Gutsy and 2.6.22

>From what I see the main problem now is the Screen Brightness. With
the thinkpad-acpi module loaded from 2.6.22. It is inverted on how it
can increase and decrease the brightness. Also it seems to not
increment either. It's all the way up or all the way down. Now without
the thinkpad-acpi module loaded you just can't change the
brightness...like it's fighting it so it can't change it and stay.
It's a little odd.

I would say upgrade to 2.6.22 kernel and make sure to load thinkpad-acpi module.

I'm glade you brought this email to the list, because I was intending
on doing thesame thing very soon.
