I'd say the ThinkPad BIOS is reporting that the device is permanentely
disabled or not installed as far as thinkpad-acpi knows, but I need data to
know for sure what is happening.

Load thinkpad-acpi with the debug=0xffff option, and send me the kernel logs
it will produce.

Good. It is software. Let's track it down. Just in case, and in order not to
waste much time chasing ghosts, please do a clean recompile/reinstall of
your kernel and boot loader, and make sure you don't have older/broken
kernels and copies of thinkpad-acpi lying around anywhere in your disk.

First things first.  If the other mentions of the issue you found were also
from Ubuntu users, open a bug about it in Ubuntu Launchpad, and send me the
LP# (bug ID or URL to the bug page).

I am the kernel maintainer for thinkpad-acpi.  Thanks for the offer, I might
have to take you up on it if it is indeed a bug in thinkpad-acpi, in order
to test the fix.  But for now, the debug output of thinkpad-acpi would be a
good starting point...
