I would look through a driver which was already converted and see what was done. vr(4) doesn't look to be a bad choice, since it was done in stages, so there are small commits you can look at (look at jason@'s commits in October 2003).. http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/if_vr.c It will be easier to do this with the card in an i386 box so you can test things in stages.
