Hello,

Considering the target of user-level drivers, I've come to a few biting
points:

- we should have a PCI arbitrer in the end.
- that arbitrer should permit to confine drivers to resources of only
  one PCI device, no more (though of course with DMA, without IO-MMU,
  you could access anywhere on the machine, but that's way less
  probable, and still the arbitrer might be able to govern them).
- so the user-level interface we are discussing at the moment will
  probably just be replaced at that moment.
- so do we really need to polish it yet more, or else simply start using
  it, and see what's broken in it?
