Brightness control with keyboard and XWindow

[Vincent Lefevre <vincent@vinc17.org>]

I can do brightness control on my PowerBook G4 with Fn+F1 and Fn+F2,
but they generate keypresses of keysym 0 (^@) and confuse applications
that get them.

xev says that they correspond to keycodes 101 and 212.

ay:~> xmodmap -pke|grep '101\|212'
keycode 101 =
keycode 212 =

Is there a bug in the kernel or XFree86, or should I add some
configuration with xmodmap? In the latter case, what should I do?
