I can see how they would do this, but I still find it worrisome. I would
guess that if the BIOS knows about a particular device it sets bus master,
but it is hard to say. I would still not want to take standard BIOS
behavior as a rule, given how many things that standard BIOSes seem to get
wrong :-)
