Bug#465864: xserver-xorg-video-ati: xserver freezes the computer on startup

[Jiří Paleček]

Hello,

I prepared a new (better) version of the patch. Please consider applying  
it or otherwise fixing the bug.

Some comments:

The first patch causes abort instead of hangs when PLL computation fails.

The second changes the algorithm so it doesn't miss any solution which  
might be better than current and finds a solution iff there is one.

The third patch removes a condition which seems to be bogus for me - it  
cannot force pll->reference_div in the solution, but will probably poison  
the solution with a bad solution having good ref_div, for the next ref_div  
to override it with a better solution.

Regards
