Matthew, thanks a lot!
Here is a new variant of the camlib.c patch:
http://people.freebsd.org/~avg/cam_get_device.2.diff

I tried to preserve 'n' behavior (and added 'e'), but in a little bit more
elaborate fashion.
Instead of just checking for a leading 'n' I try to check for a known "non-rewind"
peripheral name between the 'n' and unit number.
I am aware only of sa(4) driver with such a feature at present.
