xorg.conf

I have got Thinkpad T400 + dock station and two 24" (1920x1200)
monitors. One of monitors is connected to VGA, the second one is
connected to DVI.

I've built:
 - kernel 2.6.33-rc6 + drm-radeon-testing with enabled KMS;
 - lastest xf86-video-ati from git-master;
 - Mesa 7.7;
 - libdrm 2.4.17 with --enable-radeon-experimental-api.

After loading module 'radeon', kernel switches on monitor which was
connected to VGA, but screen is blank. Notebook panel still works and
shows console.

After starting of Xorg, xrandr reports that monitor connected VGA is
working but it's still blank. DVI monitor works fine (I have to
disable VGA monitor or notebook panel to get it work).

I've tried to set different options with xrandr to get VGA monitor
work, but unsuccessful. xrandr reports that everything is Ok, but
screen is blank.

Any ideas how to solve the issue? What additional information do you
need to diagnose the problem.
