Log:
It turns out that Intel's i82365sl-DF step has the same ID as the VLSI
82C146. The Intel i82365SL-DF supports 3.3V cards. The Step A/B/C
parts do not appear to support this. This is hard to know for sure
since it was deduced from "compatible" parts' data sheets and the
article mentioned below.
Rework the VLSI detection to be a little nicer and not depend on
scanning cards twice. This would allow bad VLSI cards to coexist with
a good intel card, for example. We now detect i82365SL-DF cards where
before we'd detect a VLSI. For the most part, this is good, but we
run a small chance of detecting a single slot 82C146 as a i82365SL-DF.
Since I can't find a datasheet for the 82c146, I don't know if this is
a problem or not.
This work is based on an excellent article, in Japanese, by NAKAGAWA,
Yoshihisa-san that appeared in FreeBSD Press Number 4. He provided a
patch against PAO3 in his article. Since the pcic.c code has changed
some since then, I've gone ahead and cleaned up his patch somewhat and
changed how the code detects the buggy '146 cards.
I also removed the comment asking if there were other cards that
matched the 82C146 since we found one and additional information isn't
necessary.
