The driver has been imported, and is included in NetBSD 2.0.

The first version was imported the day after the pointed-to
message above (21 April 2003), and it seems that the last "real"
fix to the driver was applied in the mid-October 2003 timeframe.
I see that it doesn't have a manual page (yet); we need to deal
with fixing that...

One of our local machines have such a controller, and I can
confirm that it works quite well:
