I gave it a try but i still don't get it to run on my notebook panel. The 
probed modes seem to be fine now, but i get the following error message:

chosen: dotclock 78857 vco 946285 ((m 138, m1 22, m2 16), n 5, (p 12, p1 1, p2 
clock regs: 0x90810000, 0x00051610

Fatal server error:
Couldn't find PLL settings for mode!

Without this fix it was possible to switch back to VT, this is no longer 

I'll attach both logfiles, one with the fix and one without.
