This seems to look sane in general. However, before I merge this:

- This needs to wait for a proper headers sync, which can only be done
  after the Linux code hits upstream. Shouldn't be long, I guess (I can
  queue on a staging branch while waiting.)
- As I don't have the hardware, I cannot run more than some generic
  "verify it does not break anything" testing. So, I'd like to see a
  Tested-by by someone who actually does have access to the hardware.
- I'd like to see some more review/acks from others. If other (minor)
  things crop up, I'd prefer a respin (I don't want to juggle too many
  "minor changes"...)
