radeon-mergedfb:xrandr displays negative frequencies

[Soeren Sonnenburg]

Dear all,

I am using the radeon mergedfb (clone mode) on xorg 7.1. When I type
xrandr on the console I get negative Refresh rates which confuses all the
display resolution changers out there:

 SZ:    Pixels          Physical       Refresh
*0   1280 x 854    ( 508mm x 318mm )  *-15700
 1   1280 x 1024   ( 508mm x 318mm )   -344
 2   1600 x 1200   ( 508mm x 318mm )   23793
 3   1680 x 1050   ( 508mm x 318mm )   -2502
 4   1920 x 1200   ( 508mm x 318mm )   28013 -15700
 5   1024 x 768    ( 508mm x 318mm )   -15696
 6    800 x 600    ( 508mm x 318mm )   -15703
 7    640 x 480    ( 508mm x 318mm )   -15711
 8    400 x 300    ( 508mm x 318mm )   -15714
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none
