Hi, same problem here.
(BTW I'm sorry to have filed a duplicate bug; yesterday I couldn't find this thread).

IMHO it could be a kernel problem (conflicts between modules or else). If I run "showkey -s" within a VT, I get the following output, just by pressing "brightness up" (even if not releasing the key, which has no efects at all):

    0xe0 0x54 0xe0 0x54 0xe0 0xd4 0xe0 0x54 0xe0 0xd4 0xe0 0xd4 0xe0 0x54 0xe0 0xd4

and pressing "brightness down":

    0xe0 0x4c 0xe0 0x4c 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc 0xe0 0xcc 0xe0 0x4c 0xe0 0xcc

Similar results with "showkey" without -s parameter (instead of two bytes groups it gives three bytes ones).

My system is a Dell Inspiron 9400, Ubuntu 8.04 LTS x86_64, up to date.
