See:

  ftp://ftp.netbsd.org/pub/NetBSD/misc/jdc/installboot.diffs

for some patches to installboot to add the RAIDframe offset to the block
list installed in bootxx.  A minor annoyance is that it will find your
FFS partition details first if you didn't zero the start of your disk
before changing the partition type to `RAID'.  I'm not sure if it's safe
to let it search for `raid' partitions before `ffs' (see the notes in
/usr/include/ufs/ffs/fs.h about hunting for superblocks at 64K offset).

>   /boot skipping over the raid header so it can load the kernel from RAID

I'll try and look at this in the next week or so.
