Just FYI:

I had the chance to run NetBSD-1.1-Release on a combination Octec
Rhino 9 / 512kB Cache and Cyrix 686-133 CPU. With a harddisk installed
which I took out of my terminal server the system booted
NetBSD-1.1-release and identified the CPU being a 486. Besides a few
messages about unknown vendor codes the System appeared to be fully
functional. Running dry (a dhryston benchmark utility) this system
scored 258000 dhrystones which IMHO is very respectable.

In case you like to test your system, the source code for dry is available on
ftp://ftp.ping.apana.org.au/pub/unix/dry.tar.gz
