    radeon: don't setup Xv on rn50


1. First try kernel 2.6.32 and  this stack _in UMS mode_, run glxgears
(important).
2. reboot into D.R.T. kernel (2.6.34-rc3)
3. load radeon (in my config  i have KMS enabled by default).
4. observe perfect spectex demo
5. power off machine.
6. wait  few mins.
7. Power on machine, boot 2.6.34-rc3, rc4
8. load radeon (it will defaulted into KMS)
9. startx
10. observe black screen/horizontal black bars in mesa/progs/demos/spectex
11. Verify what this effect survived warm reboots.
12. repeat "fix" described in 1, but reboot machine machine instead of powering
it off.
13. Observe same persistence ("fix" survived warm reboots)
