I think so.  (I did them for 1.1++ originally, and tried to backpatch them
into 2.something, then sent 'em off to Bruce.)

They were based on the NetBSD code; I got them from the original author,
John Vinopal, and worked them into FreeBSD.

They seem to work; at least, my ESP card is recognized.  I never did the
work for the multiport versions, because I didn't understand how a multiport
card was supposed to be config'd ;).

I don't know how much, if any, advantage they have over a simple 16550,
however.  When I did the port, Bruce said he didn't think there would be
much improvement, if any, so...

Sean.
