I think there may be several different issues here: 
1. blinking when probing displays
2. unstable display all the time

If you have an unstable display all the time, please try Dave's drm-fixes
kernel tree:
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-fixes

If you just have display problems when probing the displays (either manually
with xrandr or polling by kde) you'll need to disable the polling.
