I have just fixed a kernel that seems to work rather stable on 
at least MicroVAX II and III. I would be glad if you who are
running NetBSD 1.1 could download it and try to boot, and then
send me mail about how it works. If it works good I will make a
snapshot available. 

The kernel is located at ftp.luth.se:/pub/NetBSD/vaxport/ and is
called netbsd.

Good luck!
