(In reply to comment #33)
I booted into kde 4.7.0 with a 3.1.0-rc2 kernel and then I did:
echo 7 > /sys/module/drm/parameters/debug
and then I launched glxgears (and didn't close it).
Then I did:

I can read this in the xrandr --verbose output:
VGA-0 connected 1280x1024+0+0 (0x63) normal (normal left inverted right x axis
y axis) 338mm x 270mm
Identifier: 0x57
Timestamp: 40354
Subpixel: no subpixels
Gamma: 1.0:1.0:1.0
Brightness: 1.0
Clones:
CRTC: 0
CRTCs: 0 1 2 3 4 5
Everything seems to be crtc 0 (and I have only the vga cable connected to the
monitor vga output).
I have Pageflipping off, SwapBuffersWait off.
