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)..

It will be easier to do this with the card in an i386 box so you can
test things in stages.
