After the upgrade mentioned below, glamor+tearfree also manages 60fps now.

I have upgraded the distro to full 64bit now (kernel and apps). That involved a
forced upgrade of KDE desktop to 4.0. That one has the compositor set to OpenGL
3.1 .
I haven't seen the intermittent hangs with this upgraded system ever.
Everything in the desktop is smooth and performs fine (except real OpenGL apps
of course, due to the low GPU:)). I tried both glamor and EXA. Maybe KDE 4 is
using the GPU more properly.
So I've settled on glamor, as you say it is the way forward.
Let's close the bug until I can reproduce it again. Thanks for the cooperation.</pre>
