Here are some results I have seen on a 486DX50 with 16M.

Working drivers:

drivers/net/smc-ultra.c

Non-working drivers:

drivers/scsi/seagate.c
drivers/block/xd.c
drivers/block/cmd640.c


lmbench 1.0 results:

The OS Pipe and TCP numbers are alittle distrubing. I'm going to
re-run to double check.
