That's great.  Thanks, Alan!

I just remembered that a GENERIC kernel does not like to boot from cd0a;
that will keep us from booting GENERIC from ISO9660 in non-emulation mode.
I believe the bug is in sys/arch/x86/x86/x86_autoconf.c:is_valid_disk(),
which is missing a 'cd' clause.  Perry Metzger has also analyzed the
problem, more deeply than I.
