This bug is particularly important to fix for kubuntu users. In ubuntu,
blacklisting the video module gives a working desktop environment, as
gnome-power-manager apparently handles the backlight by some other
means. The KDE power manager, however, doesn't seem to have this
alternate way of controlling the backlight.

I personally think the importance on this bug should be bumped as it's
1) a regression, and 2) really bad for laptop users wrt power
consumption and battery life. There are reports that the issue indeed is
fixed in 2.6.29, so I backport should be possible.
