I have this problem as well, it started yesterday. Running squeeze
with all available updates. It broke my keyboard autorepeat in X, but
worked fine in virtual consoles. Noticed continuous ^@^@^@^@ in VCs
after killing X, it even prevented me from logging in on a second VC
for awhile, but that seemed to resolve itself somehow. xev showed
keycode 232 and 233 being continuously pressed and released, which on
my laptop is Fn+Up and Fn+Down, mapped to xf86brightnessup and
xf86brightnessdown. Rebooted and the problem appeared to be gone until
I tried to adjust brightness by using Fn+Down, which caused the
unending key press events to start again. xset has no effect. I'll
boot a LiveCD shortly to see if the problem occurs there. I have my
caps lock key mapped to escape, so I will try remapping back to caps
lock to test if this has any effect.
