Is this known to effect KT133A chipsets as well?  I've been using my Vortex 2 
on an Abit KT7A-RAID (KT133A based) for several days now, and I've never had a 
single lockup...  It's never been more stable, actually (compared to the 
4-Front drivers I was using with my CS4630).  The only problem I've had is an 
occasional crackle in OSS emulation mode with Rhythmbox.

I don't know.  Maybe there's more to it than just the VIA chipset?
