nm tells me module_register (dugh) not module_init.

For me, no amount of dumps on anything will produce a crash dump. On my
laptop it just says bad dump device and on my server (which is not crashing
now) I get a count down but no crash modules are produced.

btw, these are 100% elf and I don't think the panic is a smp problem.

Maybe Peter will know what the problem is.
