Ok, after some lengthy irc bikeshedding with Ben and Chris I've picked up
a few more of these, but changed a few things:
- Any hunk that touched the status_page got dropped. I've looked around
  and I think I have a plan to fix that disaster for real.
- Added comments about pointer casts due to sparse.
- Dropped the intel_bios.c patch, we agreed that to be too horrible. This
  needs some serious care to be sparse-compliant.

Thanks for digging through this mess.
