Ummm- the same trick is used in a number of places- it may be that we all
die here because we're fooling with CIA setup that the prom is using, but
I'm a bit rusty at this end of the code for NetBSD to know for sure.
There've been a lot of unexplained issues/problems with a lot of this
goop- I'll be looking at the 8200 breakage this week or next (finally) to
try and fix that end of it.
Have you tried commenting this code out (i.e., forcing the rev to > 1)?
