* compat_open() still needs to get the stack module, as the callout

Browse Source 
functionality needs it.
* callout_init_mtx() now initializes the timer manually, since the stack
  might not have been loaded yet (since a device is now attached in
  init_driver()).
* Minor other fixes; the FreeBSD compatibility layer should now be functional
  again.
* Accidently put pci.c into the repository, but that was never meant to happen.
