Bug#453839: xserver-xorg-video-ati: LCD backlight control regressions on RS482 (Radeon Xpress 200M)

[Linas Žvirblis <0x0007@gmail.com>]

Package: xserver-xorg-video-ati
Version: 1:6.7.196-1
Severity: normal

Upgrading from 1:6.7.195-2 to 1:6.7.196-1 caused some things that worked
just fine to fail on HP Compaq nx6325 notebook with the infamous RS482
(Radeon Xpress 200M) video card.

1. LCD brightness control buttons no longer work. (Un)plugging power
cord also no longer changes the brightness. I can change it if I switch
to console, but on switching back to X it is restored to what it was.

2. Putting display into power saving mode correctly switches the
backlight off, but after some time it sometimes turns back on, and does
not turn off until display is put into power saving mode again.
