openssl x509 -hash

Some colleagues have been finding that "openssl x509 -hash" produces
different results on netbsd-5 vs -current (late 2011).  The results are
consistent between i386/amd64.

(The hashes are used as symlinks in a CA directory to allow finding
trust anchor CA certs; we are using a private CA.)

1) Is anyone else seeing this?

2) Is there a notion that these hashes are meant to be computed/used on
a single machine, or are they meant to be broadly portable?  The man
page doesn't explain this very well.
