I'll give you a quick pointer, but maybe someone else will give you
a better more detailed procedure.  The key is the add-symbol-file
command in gdb.  It takes an object file and an address.  Using
insmod -m (I believe - I'm aware from the office right now), you
can get the address of where a module gets loaded.  Then you use
add-symbol-file to teach gdb about this module and where it's at.
