I don't know what the authenticate deal was.. I think I needed to be
running 'auth2 -chk' on the second machine, which the vice-setup scripts
didn't quite specify right.

Anyway, so I was just able to authenticate to my replicated (on both ppc
and x86) coda realm, and 'cfs mkm' a test replicated volume. (I didn't
want to screw up the rootvolume).

So, my first torture test is untarring the linux kernel. As long as both
servers are connected from an x86 client, it seemed to be okay (but 
reeeeeeeeeaaaaaaaaaaallllly sloooooooooowwwwwwwww).

I suspended the tar and did 

hozer_at_maxine testrep$ cfs wbstart .

Which immediately caused venus on the x86 client to sig11
