Only in the sense that i've been "writing it" for the better part of a
year now...

what does "probing based on I/O addresses" mean? _certainly_ i never
said that, since i have no idea what you mean by it.
There's definitely no requirement in my code that devices have I/O
addresses. I dunno what hat you pulled _that_ out of.

Even if:
(1) it's necessary to make the port run at all,
(2) most of the port is in the source tree,
(3) the code in question is distributed _only_ from
ftp.netbsd.org?
Of course, if you know it's necessary for NetBSD/Alpha, and you don't
bother to look at the NetBSD/Alpha sources, then you still are missing
something.

You've pulled a weird case -- that i don't recall talking to you
about, EVER, and which i certainly don't disallow in my code -- out of
your hat...
