Have you tried putting DDB into the kernel, and tried to
hit ALT+CTRL+ESC to go into the debugger on the hang ?

Printf is a good tool here, sprinkle your source with
printf's so you can see how far you get, and what 
essential values are getting used.

Another possibility is to attach 8 LED's to a printer
port, those you can then turn on/off at will by a simple
outb statement. I use a 2*40 char LCD display connected
this way sometimes, that gives me a history of 80 values,
so I can se the exact sequence of events that let me to 
the problem at hand..
