If we can't probe the RTL80x9 for some reason, fall back to probing it

Browse Source 
as a Novell NE-2000.  This is necessary for unpatched qemu working
correctly.  qemu claims to be a RTL8029, but doesn't implement the
RTL8029 specific registers at this time.  I've created patches for
that, but there's no reason we can't use qemu's emulation w/o these
patches.  This should make life easier for those folks that boot
FreeBSD via qemu.
