Sorry, I meant "others recall it being mentioned that 7.3-2 should 
work".

Right, VSI Alpha will cluster with VSI X86.  But the important point is 
that DEC/Compaq/HP(E) Alpha can cluster with VSI Alpha, so I can do a 
rolling upgrade to VSI Alpha, then a rolling upgrade (which of course 
will be a fresh install, but the cluster is upgraded in a rolling 
manner) to x86.
