Hm. It would be a check if the given DMA channel is active - and if it 
is busy waiting for it.

So, what would then be a generic interface for DMA? I see that this is a 
verrry basic solution - but where do you see the actual problems 
implementing this interface for other DMA controllers? Or do you think 
that the interface is to simple?

I haven't given up on the general solution yet. If I don't see another 
way I will do that.
