It works with KMS disabled (16 / 24 bit depth).

It also works with 24 bit depth and KMS enabled.

Only with 16 bit and KMS enabled it does not work all time...

Tested resolutions (all 3 cases above):
800x600   @ 76 / 75 / 70.7 / 74.9 / 65.3 / 60.3 / 60 Hz
1024x768  @ 76 / 75.1 / 70.7 / 74.8 / 65.3 / 60 Hz
1280x720  @ 76 / 70.7 / 65.3 / 74.9 / 60 Hz
1920x1080 @ 60 / 59 Hz

I will try it soon. If it is not also "fixed" with 24 bit depth I will post
log/config files.
