Description of problem:

With KMS and dual display the external display is fine, but already during boot the laptops display looks like the horisontal sync is off/missing.

I assume it was introduced with
* Wed Apr 15 2009 Dave Airlie <airlied@redhat.com>
- drm-modesetting-radeon: fix rs690 video (#492685) + add bandwidth calcs
* Tue Apr 14 2009 Dave Airlie <airlied@redhat.com>
- drm-modesetting-radeon.patch: more bug fixes
(it "worked" with -70 - see bug 496333)

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
