   Wow, does that really work?  Don't you have to at least drop a sparc
   disklabel onto it, do the mount, and then go back to an alpha disklabel by
   rewriting the label and alpha bootblocks with cross-compiled utilities on
   the sparc? (A second drive, even an crummy old tiny one would really make
   this a lot easier, because then you could obviously dd(1) cdhdtape onto it
   and then rewrite the labels and stuff from NetBSD/alpha.)

this works for the 'c' partition.  :-)  i have used this a number of times.
