Restoring 8.2 to 8.0

I have a dump from 8.2 restored to file that was pg_dump'd with format c
from a production server. I want to know if it is possible for me to
restore this to a 8.0 development server where I am not able to upgrade
at this time. Trying to do some testing, but this is the only other
server that's available right now. I tried a normal restore and start
getting errors relating to regclass:

honeypot:~ # psql -U postgres trax < pgtrax.sql
<snip>
ERROR:  cannot cast type text to regclass
ERROR:  relation "public.tblmenu" does not exist
ERROR:  function nextval(regclass) does not exist

Is there a way I can prepare my dump to work? There is a lot of data, so
I need to maintain COPY methods of inserting.
