I'd like to see the changes and associated config file.

I would advocate against creating a config file called
arch/pmax/conf/PMAX.  I really don't like the way the name "pmax" is
overloaded, meaning both the NetBSD/pmax (Decstation/Decsystem) port,
and a specific model of DECstation. Having a kernel config called
"PMAX" just makes that worse, IMHO.
