But the pci is truely newbus'ifed. The usb code doesn't make proper
use of newbus, and is really just a port from NetBSD. So, it's a bit
different. Also, usb is different than PCI in that it has well documented
"device" interfaces. So unlike PCI there is a more limited number of
device drivers. With your statements I do agree that any device drivers
that aren't part of the spec should be located else where, otherwise we
should break down PCI even more than they are now.

If you do the work for the others, I'll make usb follow that, but right
now I'm most interested in cleaning up the usb support. Also, the ether,
disk, etc. has no precedence compared to the others.
