Hello Alex,

thank you very much. This helps a lot.

But I do not really understand why this is suitable as an output
option. If I understand it correctly, the problem comes from
invalid BIOS entries for the PLL tables.

So this is IMHO a model specific (or even hardware specific when
BIOS is counted as part of hardware) setting and this may be better
set by an xorg.conf-Option in the device section.

Making this an output attribute will cause in my understanding that
the server will start with probably wrong values for the PLLs because
the setting with xrandr is possible only after the server came up.

I understand that it is a goal to make as much as possible
configurable by xrandr but I think there may remain some fundamental
hardware specific options (PCI, AGP and maybe also such BIOS options).
