Who said they were?

The Netatalk package is several parts: afpd, the file server; atalkd, the appletalk network stack; papd, the appletalk printing server; and a couple of other little things.

In any case, afpd supports both appletalk and TCP/IP connections. Without afpd, Linux cannot use AFP over any network protocol.

In any case, I'd try updating netatalk before anything else, and maybe check out the netatalk support on SourceForge.
