Hi again, Thomas :)

I have a system not dissimilar to yours.. it's a P3-1GHz with PCI Radeon
7000. OS is Ubuntu hardy with the patches from your 0.0.2 release. 

Now that I've got the patches in place, I get a stable desktop display
on the TV. 

If I start vdr / xineliboutput, the picture will be Ok for a second..
then it'll move up and down (like camera wobble, but it moves the
onscreen logos / VDR menus, too!).

I see this kind of thing at least once per second :

[ 2706.402871] [drm] changed radeon drift trim from 00520125 -> 0052018c

If I quit vdr (leaving X running), and run the 'drift_control' tool, I
see a drift speed of approx -3900 for 4 seconds, then +16000 marked 
'excessive drift speed'

It's much the same story on the output of the 'startx' console..  lots
of  <- resyncing field polarity M1 -> and  

sync point displacement:       -365
drift speed:                 -13004 excessive drift speed
overall compensation:          -461 

every couple of seconds :(

The system has no load since it'll become my new VDR box (hopefully :)

Cheers,
Gavin.
