With "KMS" enabled I could not set "tv_format".

What I configured:
 - Kernel:
     2.6.31, 2.6.31-next-20090918, 2.6.31-next-20090926, 2.6.31-git17

   with module i915 and KMS enabled

 - xorg: xf86-video-intel-2.8.1, xorg-server 1.6.3, randr 1.3

then I run:
> xrandr --prop

I got:

with:
> xrandr --output TV1 --mode 1024x768

I could set "1024x768" (see the greyed output an TV, currently a
terratec grabby usb, viewed with mplayer), but the output is
black/white.Then I tried:

> xrandr --output TV1 --set mode PAL_B

The TV picture is flickering for a short moment, but the result is
unchanged.

In /var/log/messages I got "[drm] TV-8: set  mode 2d".


If someone outhere has a working setup, please tell me.
Thanks for hints.

regards
