Just to clarify, (not sure if it makes any difference to the kernel) it 
is a dual cpu, not dual core system.  The only thing that makes me 
hesitant to believe it is video card related is the fact I have tried 
two ATI cards, with the Proprietary ATI drivers also.  I will admit 
however that it is MUCH more stable using the out of the box vesa driver 
than it is with either the ATI of NVidia driver.  In this regard I think 
you may be on to something :)

I really honestly want to rule out bad hardware, as I can seemingly run 
memtest, and other CPU/Mem/MoBo intensive tests forever without a hiccup.

Thanks for your time John
