Well, even with the KT133 chipset, I needed this for being able to *just view*
progs live on the ARD transponder:
setpci -s 00:00.0 latency_timer=0
I haven't tested the MVP3 w/o above, but I guess this is no better.

Unfortunately I mostly have Via crap lying around here. Only my main machine
has nforce2... I also have some Intel TX chips lying around, but I guess CPU
(~166MHz) isn't strong enough. :-/
Well, thanx for sharing your experiences. I at least now now that I am not
alone with this.
