 I have prepared a patch and will test this on amd64 and amiga.
 See f.n.o:/pub/NetBSD/misc/mlelstv/setroot.diff.
 
 There is an issue with hp300 and hp700. In cpu_rootconf() they
 call setroot() and then catch the root device and partition
 so that the MD code can later reboot from the same device.
 
 This can't work when setroot is only called later.
 Maybe the code could be moved into cpu_reboot().
