Sounds like you could use #nvidia on irc.openprojects.com.

They've got a the latest drivers (usually before nvidia posts them on
their site), a script to "check" the installation (warns about the files
you mention that have to be removed/renamed), agpgart backports (from 2.4
to 2.2), and lots of other goodies, not to mention a patch for the
NVdriver module to compile against 2.4.0-test10 & 11.
