Wow, I'm even more sad than before.  Just for grins and giggles I tried 
the regular k7 kernel, and it locked up as well but I was able to move 
the mouse.  It appears that I may have something else going on here.  
The only kernel that I can use that doesn't cause a lockup is the 
regular 386 one.  Where do I begin to try and figure out what's wrong?
