This was caused by a too old firmware. It netboots well since I updated
the machine to the latest (Open)Firmware.

This was caused by not mapped interrupt controler registers. I fixed
this in my local source tree.=20

There is an other bug with the (e)siop(4) driver. It crashes when the
on-board RAM is used. A work around is to disable the on-board RAM in
the MI (e)siop(4) driver. This is no real solution, it only cures the
symptom. I have to dig further into this. Once I found this I will
commit all fexes and request pullups to 2-release.

If someone needs to run NetBSD on a 43P-140 right now I can supply
source patches and patched kernel binaries.
