* [ Bug 6966 ] large negative refresh rates reported

* [ Bug 6309 ] radeon/r128 fails to read hsync/vsync rates when rang
*              descriptor is missing
* [ Bug 5473 ] Blank screen with Radeon Mobility X700 (Acer Ferrari 4005)
* Reboot should not be needed for external CRT to function when connected
  later on Ferrari 4000
* Modes need to be sorted, and sorted correctly
* Provide all resolutions (instead only the largest one) in MergedFB clone
  mode without config file
* Bump up clock rate for ES1000 to allow higher resolution
