If you leave the port debug knob for drm-current-kmod AS-IS, I think you 
can get away with:

make DEBUG_FLAGS="-g"

Then re-load the vmcore file in GDB/KGDB from ports (!) and add the 
symbol files for the modules loaded. Then get the backtrace using bt 
command.

BTW: Did you try drm-devel-kmod for 13-current?
