Result of the investigation so far: DRM seems to locate a buffer or so
at a fixed offset, which points directly into the kernel data segment.
One thing he's overwriting the ipfw_chk_ptr, which produces the panic.
Matt, do you have an idea how to force a coredump or so and helps us
determining the exact location? Putting a watchpoint in there just
hangs the machine.
