I have rehacked on a fresh 6.7 and confirmed that it works. Actually the install file didn't change, but the cp2_megamods.pl file did, and i tested it out to remove the megamods properly. You may need to readd the megamods then delete them to remove the status.
If you followed the instructions correctly, the custom avatars/polls should have the megamods at the bottom of the list, and they will work correctly. If you do not, rehack cp2_lib.cgi and cp2_membermanage.cgi.
