I have been messing with it today as well, and I was
successful in finally getting the drive to write
straight through. I did:

mt -f /dev/nst0 drvbuffer 1
dd if=boot.fs of=/dev/nst0

By turning on buffering, it wrote cleanly. I can now
boot the tape on the Vax (sorta) - I was able to get
the boot loader to load, then it dies. But I think I
have solved the "tape writing" part of this.
