I can't really right now :( My notebook with RV620 died (hard disk
ended it's life and power cable got broken). I hope to resurrect him
in about a week.

If that isn't needed on R6xx, I'm not sure why we implemented it in
first place at all. Christian? Do you have idea why this was required?
I remember than in first place we were using timer, then we switched
to the interrupts. But why we needed it at all?
