On IP22 the PROM uses SystemPartition to find the kernel/bootloader.
We set it to something like scsi(0)disk(1)rdisk(0)partition(8) to grab
it from the vh. Is SystemPartition used differently on IP27?

Well we could either check if OSLoadPartition matches the linux device
naming scheme or the other way around and see if it looks like a valid
device identifier used by the PROM (I'd prefer the later, though) - or
simply make the OSLoadPartition <-> root= mapping '#ifdef CONFIG_SGI_IP22'.
