Yes, that's what we've been saying to do.

Copy the data off of the old drive onto your new machine in the same
place.  For a RH install of PG7.4 that will be in the /var/lib/pgsql
directory I believe.  Make sure everything in the dir is owned by
postgres on the new machine, and the perm on the /var/lib/pgsql dir is
0700 and try to start up the db (sudo /sbin/service postgresql start
for an rpm install)
