RADEON: final fix for RMX/LVDS
It seems that on quite a few laptops the LVDS H/V timing
from the bios tables are way off or just doesn't work period.
Either we are using it wrong or we need some additional checks
when we parse it. Only the dot clock seems to really matter,
so use cvt modes and update the dotclock. This seems to work
correctly in all cases.
