  Agreed, it is my opinion, and I try to work that into my reviews of
drivers.  I would, however, like it to be more an architectual
requirement, and would be willing to make some arguments or proposals
in the near future (it would be real nice to get my current project
into Solaris).

  As Garrett, I am in agreement, and am more than willing to work with
and/or sponsor such an effort (though again, after I integrate my
current set of bits).  Garrett- you in for a collaboration here?
