I just went through this mess myself.  Only the hard drive is the same.  
I used Silverlining to make the (Mac) partitions which I converted using 
mkfs.  Another one or two on the OpendBSD had the same problem.  It's 
gotta be the drive.  The way the two of us worked around it was to 
install on the first part of the disk.  If I recall correctly, he used a 
80 meg root and a signicantly larger, but not too large usr.   I ended up 
using a 500 meg root+usr.

None of us could say what's causing the error.   I suspect that it won't 
install if the partition crosses the 1023 cylinder limit.  Others report 
a mismatch between the drive geometry (C/H/S) reported by mkfs and ffs.  
One who got it to work got a minimal system going on a small root at the 
front of the disk.  Then used *BSD to install the rest--thus he was able 
to report the geometry mismatch.  The rest of us, like you, couldn't get 
that far.

BTW, I ended up installing NetBSD vice OpenBSD because that's what the 
installer was pointed at when I finally met success :-).  (My original 
assumption was a corrupt file, so I tried both.)

I'll forward any traffic I kept from that experience to this list when I 
get home for everyone's viewing pleasure.
