Comment 5 for bug 320874

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.
