Number one rule for these things: if it is working without an ACPI module
loaded, do NOT load it.  In fact, blacklist it to make sure something
doesn't decide to load it behind your back later :-)

Ah, yes.  Video *can* help you with that.  Try it.  It is not thinkpad-acpi
that is messing with it, and be warned that thinkpad-acpi brightness support
does not work well with machines with 16 levels of brightness yet.

Try the video module. It responds to the ACPI handles, and might get things
to work.  Try it *without* thinkpad-acpi loaded first, so as to be sure
nothing in userspace will screw it up by trying to also react to the buttons
and tell thinkpad-acpi to mess with the brightness (which, as I said, won't
work well for the X61s yet).

Check the volume ones too. I think someone reported some sort of weirdness
with those.

You have more event-driven hot keys than that in your thinkpad. Use "cat
/sys/bus/platform/devices/thinkpad_acpi/hotkey_recommended_mask" to know the
best mask to use (latest ibm-acpi.sf.net patches).
