Which happens to be the ONLY proper way to deal with Volume-change keys on
the T61 and X61.   In fact, Lenovo itself made sure of that, ON PURPOSE.

Note that thinkpad-acpi knows about it, but someone decided to break its
configuration in userspace on Debian, Ubuntu, and maybe other distros too
(look at your logs and you will see thinkpad-acpi complaining someone is
doing stupid things to hotkey_mask, if you have a new-enough thinkpad-acpi).
The usual culprit is either HAL or hotkey-setup.

A new enough *61 BIOS is even supposed to disable the codepaths
thinkpad-acpi uses(!) for the volume keys, in order to make it downright
IMPOSSIBLE for userspace to screw up.

Thanks for posting this.
