This is a valid concern. I wonder if we, or better you and Matthew :-),
can talk to Justin and Ken about this. Maybe it is possible to find a
for this problem. Justin, Ken, what do you think about this?

The other valid concern was about NetBSD's multi-architecture-support,
especially the amount of drivers which need to be ported. But, IMHO,
if we share the CAM code, we can share the load of writing/porting
much easier than today.
It would be great, if both, old and new drivers could coexist, though,
to ease the transition to CAM. Is this technically possible?
