I was using Ubuntu 11.10 (32 bit) on a ThinkPad W510, and having this problem. Fn+Down decreased brightness by 2 steps, and Fn+Up increased it by 3 steps.

I just changed my installation to Xubuntu 11.10 64 bit, and am having the same issue, thus it's not specific to Gnome nor KDE. I don't have HAL installed. The two commands below have no effect:

/etc/init.d/acpid stop
/etc/init.d/hal stop (No such file or directory)

The temporary workaround is described in the comment by Kuba Górski. I can also overwrite the brightness file to set the desired level (0-15).
