You have to use 7.0.x to read the 7.0 database.

Restore a 7.0.x installation.
Unzip your data directory back to its proper place.
Use 7.0.x pg_dumpall to save your data to a flat file.
Remove your data directory
Install 7.1x
Run initdb to create a new database structure.
Use psql to read in the flat file dump and recreate your data.
