Yes. I fear this will be the only clean solution to make NetBSD/amigappc run
on BPPC boards.

Another big problem left, which I also have to fix for CSPPC, is that DMA
doesn't work well. For example the ahsc(4) A3000 scsi driver will only work
reliably without DMA. Otherwise it slowly corrupts the file system.
