This is just a quick hack to see if changing the offset registers 
actually makes a difference. It just shows the value as unsigned, 
instead of the positive/negative offset it should probably show.
I'll have a look around for a more proper way to implement it, if you 
think this functionality is worth having in the mixer.

I think the problem with all the newer kernels was the pvr driver, it 
either didn't work at all, or it worked very slowly (getting < 8 fps in 
glxgears). You might have fixed up some things since I last tried 
though, so I'll give it another try.
I only tried 5.15.y recently, and that had the really slow performance too.
