For what it's worth, I agree with Scott. I'd rather see a new and

I'll just make the comment that if a separate driver is written, there
needs to be a clear way for an end user to identify what driver is
needed/preferred for his chipset. We already have cases like
re(4)/rl(4) and sym(4)/ncr(4) where some chips are supported by two
drivers - though generally only one driver fully supports the chip.
This sort of thing is confusing for end users.

Yes, this is a good point, and when I'm done I will make sure that
only the appropriate ID's will work on a particular driver so this
kind of thing does not happen.
