uVAX 3100-80 boot again

Well, I still haven't been able to get my MicroVAX 3100-80 working off 
the disks. I just tried to install the latest snapshot, but I still get 
nothing when I attempt to boot DKA0.

I did notice that the install program seemed to think the OpenBSD part 
of the disk started at sector 1153, which seems quite high. What should 
this value be? I know on i386 it's 63, and on my alpha (running netbsd), 
it's 0. Maybe I have a problem with the disk geometry?
