Ahh, that changes everything here, thanks for letting me know, I had
missed this.

The problem is that the module_init() is failing, yet this isn't really
a module, it's built into the kernel. So some of the module teardown
logic is dieing when it thinks that we really have a full module
structure here (owner and such).

I'll look at this further tomorrow, as I'm travelling pretty much all
day today, sorry.

thanks,
