In the sparc64 port, neither the bootblock nor the bootloader has this
information embedded in it.  Both interpret both the native and the NetBSD
disk labels to determine whiche file to load.  They were done this way so
moving a few files wouldn't require reinstalling the bootblock.

I really don't want to give this up.  If I can't share partitions between
NetBSD and Solaris I might as well switch to Linux.
