Wow.. I didn't realize that this was in current already. :)  How do I
go about converting my PCI device driver to use it?  Also, are there
any plans for a transition to the new module system?  (elf as well?)

Have you taken a look at NetBSD's bus code?  They seem to have abstracted
things fairly well..  Also, it might be interesting to look into their
bus dma framework as well.
