I think this collides with SUN disklabels, needed for bootable SUN CD's (Sun3,
Sun3x,32 bit Sparc - I'm not totally sure about Sparc64).

Hm, VAX disks will also need block 0, afaik.

(Can we build a first word that's a valid Hp700 branch and VAX CALL, like the
evil VAX+PDP11-machine-code array from some IOCCC?)

Maybe the documentation should have a table indicating colliding requirements
for booting, for people who generate multi-architecture boot CDs.
