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.
