Uhm... but thats not the issue i am talking about ... its the fact that it
doesnt set up a good environment to boot NetBSD in ... If you look f.e. at
the ../syssrc/sys/arch/arm32/riscpc/machdep.c you'll see what a trickery
is needed in order to get it running compared to
../arch/arm26/arm26/machdep.c and start.c you'll see the difference ...

Hehe... well you could f.e. mess around with the pages (swapping or
reordening them) *before* you start the kernel instead of starting the
kernel who has to mess with itself !
