What version of {Net, Open}BSD are you running, out of curiosity?  To use
an 040, you will probably need newer than 1.2 (i.e. a -current GENERIC
kernel and preferrably the accompanying base121 package (I doubt the
others changed enough to worry about, expect maybe comp121?).  Beyond
that, I'll leave the answer to this question up to folks w/ more kernel
hacking experience.  :-)

I doubt most of the ppl here would accept payment for NetBSD hacking even
if you could.  Hence the phrase volunteer effort.  :-)
