    Greetings Troy:

That sure smells like a memory issue.  Though the rest of the message leads 
me to wonder if it is a mb problem.  A good way to verify your memory is by 
running memtest86:
memtest86 - A thorough real-mode memory tester.  <from apt-cache search>

This lets you boot onto a memtest86 kernel and starts running a series of 
tests on your memory.  I just added a lilo.conf entry for the box I was 
testing, and it worked very well.

Good work.  I have heard many horror stories about video cards.  I do not 
know of any hardware tools, but I bet there is a Debian user that may have 
some ideas.  I also have a box that gets silly in my shed.  I have a feeling 
that it might actually be the AMD cpu :(

Best of luck to you.
