Umm, you didn't run crashme as root, did you? The above certainly looks like
that (bad arguments to the sys_init_module()" system call, but it should
never get that far unless you're root).

Now, running crashme as root is "a bad idea". A _really_ bad idea.

True, but trying to bullet proof root from crashme as much as possible
is still a good idea. Yes, we won't be able to protect against a random
program which just happens to open /dev/mem and scribbles all over it.
But we should be able to protect against bogus arguments to system
calls....
