I suspect that the problem here is that the user is expecting a recovery
tool released nearly 5 years after the OS he has installed to work
without issues.

I'd suggest that if etch supports the new superblock checksum format,
this bug can be closed, as we no longer actually support sarge (in a
distribution sense - Martin, if you want to make it easier for sarge
users, that's of course entirely fine).  I've downgraded the severity
for now, as a bug that only affects sarge users does not affect the
releasability of this software in squeeze.

Cheers,
