Description of problem: On a Dell XPS M1210 if I try to adjust the screen brightness (Fn+up/down arrow) the Xserver crashes. Pressing the same keys in one of the tty screens gives atkbd.c: Unknown key pressed (translated set 2, code 0x85 on isa0060/serio0) atkbd.c: Use 'setkeycodes e005 <keycode>' to make it known Nonetheless, the brightness *is* successfully adjusted. So, I'm unsure if this is a kernel bug or an Xserver bug. But, the Xserver shouldn't just die, I'm sure. This is on a fully updated FC-6 box as of today.

Inspired by this page: http://www.thinkwiki.org/wiki/Problem_with_LCD_brightness_buttons I issued a modprobe -r video as root. Now in X, pressing the brightness increase and decrease key combinations doesn't change the brightness at all, but also X doesn't crash. I don't know if one would call that progress or not :). Certainly seems to be something to do with the video kernel module and X.

Isn't this DUP of bug 220466?
(In reply to comment #7) > Isn't this DUP of bug 220466? Difficult to say. Certainly similar hardware, but 220466 doesn't report the Xserver crashing and restarting, but rather the screen going black. I looked thru' the Xorg.log posted there, but it didn't seem to contain any kind of backtrace, so impossible to say if it's the same. It's probably related, for sure, but I'm not sure it's a DUP.
Yeah, not a dupe, this is an actual crash.
intel driver should fix this in F7 and later. It goes out of its way to suppress BIOS adjustment of the display brightness and handle it internally instead.
No intel driver update is planned for FC6, so I'm calling this fixed in rawhide.
