You should be able to use the 'sym-trace' to generate a call stack
from the dump.  Look at unsupported/scripts/sym-trace.  You'll have to 
supply the executable via '-o <executable>' and paste the backtrace in 
on stdin.

You might also try running your kernel under GDB.  Running the OSKit
hosted in Unix mode can make debugging easier.  The 'kern' chapter of
the documentation talks about GDB debugging, the 'unix-support'
chapter talks about running the OSKit on unix (but the doc may be a
bit out of date... sorry).
