>Description:
Booting NetBSD/prep with the experimental siop support on v 1.9 leads to
suboptimal results; one has to wait for all devs and luns to timeout before
boot proceeds:

$ dd if=/dev/zero of=disk seek=2000000
$ qemu-system-ppc -nographic -M prep -hda disk -kernel sysinst_small_com0.fs 
WARNING: Image format was not specified for 'disk' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

panic: call to null-ptr from 0x0

The operating system has halted.
Please press any key to reboot.

>How-To-Repeat:
	Also the kernel does not work, it needs -cpu 604 to not null-ptr.
>Fix:
	1. fix the siop probe to be more graceful.
	2. deal with the null ptr trap.
