Hi all, 

I've just checked in the changes to the boot programs that
support common boot media.  The boot programs now look for
"netbsd.sun3x" or "netbsd.sun3" before "netbsd", so boot
media can support both by providing two kernels.

This required fixing an old bug where only the first open
attempt would work (i.e wrong kernel name => loose).

Common boot media for sun3/sun3x should now be possible
with a few changes to the miniroot (still todo).
