I got it to boot now. Luckily there were no other problems than pmap
not taking fast memory and that dcbz+memory coherence issue discussed
earlier.

ftp.netbsd.org:/pub/NetBSD/misc/jandberg/amigappc/20101205/bppc-pmap.diff
There is a new option to set maximum address used for pmap allocations.
Another option disables use of dcbz in kernel. And third disables the
use of memory coherence bit bit in page tables. 
I think this is going to need some more work. Hopefully a better
solution to the dcbz problem could be found.

ftp.netbsd.org:/pub/NetBSD/misc/jandberg/amigappc/20101205/bppc-identify.diff
Some small changes to have the machine identification printed
correctly. My bppc board has type 'H' and version 7 processor is called
603ev instead of 603e+ by the common powerpc code so we might as well.
I think that this is the only part that I feel confident about
committing at this point. ;)

Also it looks like cpuclock/busclock calculation is a bit off.
This one should have 200Mhz processor instead of 233Mhz.
