That would be watching tv via kaffeine.

After taking a deeper look at dmesg, it looks like i 
found "my" problem. The Archlinux mkinitcpio script
didn't include some needed modules (agpgart for instance),
so agpmode was completely disabled.
[dmesg]
[drm] radeon: power management initialized
[drm:radeon_agp_init] *ERROR* Unable to acquire AGP: -19
[drm] Forcing AGP to PCI mode
[/dmesg]

I then added following modules explicitly to my initramfs
-> radeon,agpgart,via_agp,ttm,drm,drm_kms_helper.
Result: Still everything _but_ xvideo (kaffeine again) seems 
to be ok plus agp mode got enabled this time.

Now i disabled all radeon needed modules in the initramfs
and let kernel autodetection decide itself later what 
modules to load.
Result: Everything is ok, even xvideo(??).

Did i forget some important module, which affects radeon xvideo?
This is strange somehow. Well, whatever, it turns out, this doesn't
seem to be a real bug at all, so i'll close it.
