This all looks good. It's exactly what I was wishing for on the
previous thread. One minor issue though. Since there are MMX and
non-MMX Pentiums, there probably needs to be and MMX entry for
MACHINE_CPU and some sort of CPUTYPE for non-MMX Pentiums. I suspect a
vast number of old pentium systems turned routers are non-MMX. I think
the same holds true for SSE and i686 as well.
