Prior Red Hat kernels had Appletalk support configured in by default. This
has changed in RH 6.2 (at least as of kernel 2.2.14-12). This means that
unlike updates from 5.2 to 6.0 and 6.0 to 6.1, if you want to run netatalkd
you must compile the appletalk.o module from source and copy it to
/lib/modules/2.2.14-12/net yourself.  The ipddp.o module DOES exist but
without the appletalk.o module several symbols remain undefined so it will
not load properly.

At the very least this should be mentioned in the docs somewhere as a
caveat for the upgrade...
