VAX 4000/200 panic with 6.1.5

[Felix Deichmann <m4j0rd0m0%gmail.com@localhost>]

After (re-)acquiring Q-Bus hardware recently, I noticed that a VAX 
4000/200 "identifies" itself as Rigel CPU, in -current, too. It is the 
same SOC with tiny cache as in the VAXstation 4000/VLC, stated in the 
"KA660 CPU Module Technical Manual", EK-KA660-TM-001. Suggested fix follows.

However, my attempt to netboot a 6.1.5 GENERIC kernel on the machine had 
little success (panic). Log follows, too.
Help would be appreciated.

Regards,
Felix
