dmesg output

Monitor will keep constantly switching off/on when entering power saving mode:
 - LCD going black
 - OSD message "Entering power saving mode"
 - LCD turns off, then immediately goes back on and the cycle repeats  

This bug was previously reported on other list and should be fixed but unfortunately it's still present on my system. 

 - Gentoo/AMD64
 - kernel 3.1.0-rc6-00120 (linus + drm-fixes)
 - xorg 1.11.0/1.10.4
 - Radeon 6850 (+internal card disabled)
 - Dell U2410

I'm not sure if this is relevant but the same effect can be observed on every power mode, i.e. xset dpms force standby/suspend/off.
