no luck! i yanked the nvidia card, the drivers and made sure the nvidia 
kernel module wasn't being loaded at startup. i'm back to running off 
the onboard video on the Tyan ( 8MB ATI Rage XL ) and the problem still 
persists ( see above ). Anyone else seeing anything similar, or might be 
able to point me down a different path?

thanks,
