Here's a thread in the linux-thinkpad mailing list about this issue (it affects XFCE as well as GNOME): http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2012-February/050576.html
The thinkpad-acpi kernel module maintainer says: > This typically means broken crap that reacts to brightness *change* events as if they were keypresses.
Upstream bugs that seem related to this:
- ThinkPad X60s and X300, improper brightness adjustment using function keys Fn+{Home,End}, twice long step https://bugzilla.gnome.org/show_bug.cgi?id=579224
- Need a setting to tell g-p-m that brightness changes are handled in hardware when using xrandr https://bugzilla.gnome.org/show_bug.cgi?id=601410
