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

bus dma framework as well.
