Now this is interesting:

I have :
Epox 8KTA3 motherboard - VIA chipset
1ghz Athlon chip overclocked to 1336.42 MHz (133Mhz bus clock)
 (accidentally discovered that it could do it and still run at 40degC
  with the appropriate cpu and extra case fans)

and I get:

$ /usr/bin/time dd if=/dev/zero of=/dev/null bs=64k
count=16384
16384+0 records in
16384+0 records out
1073741824 bytes transferred in 1 secs (1073741824 bytes/sec)
        0.39 real         0.01 user         0.37 sys

Why would it get exactly the same transfer rate? Appears something
on the mb maxed out unrelated to cpu speed.

Yes 3.3.6 has several problems with the Xpert 2000. I just upgraded
to 4.1 on my machine with an ATI Xpert 2000 and it works great!
(Thanks to the precompiled xf86 4.1 that was posted)

At work, we have built several Athlon systems (Gigabyte/DDR, Asus
and Epox), and the Epox MB has been the best-natured of all of
them. We tried them with a couple different Linuxes, Solaris 8,
and NetBSD 1.5.1.  For server activities, it pretty much keeps up
with the Gigabyte DDR system for a lot less $$.
