Some smaller changes to the API will be needed. Especially the ISR
routine won't be a void function any longer but will have a return
value. I think most other changes will be hided in the structs.

Yes, I will try to implement a prototype ASAP, but this might take three
more days, as I'm out of office again for two days.
Before I'll check in anything I will send a patch to the list for review
