I can certainly do this, but I have one initial problem -- with the small
screen and no scrolling feature, I can't capture the entire stack trace.
In fact, I've commented out all the stack trace printing stuff to see what
was above it.. :)

I can get you a register dump, the location the stack trace starts at
(ESP), the call trace from that point, and what it's determined to be the
faulty linear address -- is this enough?

Thanks!
