Put the disk on another machine and use sunlabel -fixsum to edit the
label?  If it's the magic number that's wrong, copy the label with dd
bs=512 count=1 from the raw partition into a file, bash the magic
number (the last four bytes of the 512-byte file are the magic number
and the checksum, in that order), and _then_ use sunlabel -fixsum?  Or,
if you know the partitioning you want, just sunlabel -new....

Hm, I should add -fixmagic to sunlabel.

If you haven't a copy of sunlabel, I'll be glad to mail you one.
