Hmm, I will see if I can reproduce it.  Do you get that problem if you use
2.6.23 + thinkpad-acpi 0.18-20071013 available at:
http://sourceforge.net/project/showfiles.php?group_id=117042  ?

There is also a git tree, if you prefer:
http://repo.or.cz/w/linux-2.6/linux-acpi-2.6/ibm-acpi-2.6.git
for the gitweb interface, there is more data in that.  Look at the release/
branches.

The bug might even be triggered by the BIOS, but it is a real bug in the
driver.  But the new BIOS will probably behave much better re. brightness
functions.
