As long as you are seeing "cx88xx: disagrees about version of symbol
tveeprom_hauppauge_analog" then you have a bad version of tveeprom.  You
can post and post here all you want, but until you find and erase that
version of tveeprom.ko, nothing else that you do will matter.

Try doing your search this way:
find /lib/modules/2.6* -name tveeprom.ko -print

It might just be that updatedb is not being run every night on your
system and your slocate database is not current.
