Ok, I looked into the different IOMMU drivers for pa-risc and ia64. The
changes needed there are non-trival and I can't test them on real
hardware (I only have an pa-risc 1.1). So I think I skip these 2
architectures for now. They can be changed by somebody who has the
hardware :)
(Alpha instead was trival. I changed this driver)
