Linux 2.6.11.7 on alpha, OpenAFS 1.3.81

Trying to use a heimdal (new enough to have the /proc support) kinit
to get tokens; tokens lists none afterwards.  Its not impossible that
we screwed up and had an old something hanging around that made it not work.

Specifically, I want to store a token for vos.  I asked
about this on -info a few weeks ago and moose said you only 
need to have the module loaded for it to work.
