I thought it was an SiI 3112? FreeBSD 5.4 thinks it is, and if I
presume correctly that you are inferring this name and model from the
"vendor" and "dev" fields, there's some inconsistency here between
your call and 5.4's call. (Of course, I'm probably just ignorant of
these things and there's data I don't have.)

If someone needs to access the box to test code, I'm willing to assist
by providing an SSH login. I haven't done kernel device drivers since
college, and while I am a quite capable C programmer, I would prefer
if someone with more experience did the work.

Alternatively, is lifting the code that "properly" identifies this
from FreeBSD 5.4 ok?

No, with the caveat that I haven't put it under heavy load yet.

How can I test this? :) ("dd" comes to mind...)

History is not usually what has happened.

History is what some people have thought to be significant.
