Bug#372918: negative refresh rates in xrandr

[Soeren Sonnenburg <bugreports@nn7.de>]

Package: xserver-xorg-video-ati
Version: 1:6.5.8.0-1
Severity: normal

when I look at the output of xrandr I see negative refresh rates not
only confusing me but also e.g. gnome-display-properties (i.e. I can
no longer change resolutions on the fly with that tool)

$ xrandr
 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

I am using MergedFB on a titanium pbook 15". Here is the relevant device section:
