You can also specify architecture of specific packages in the kickstart 
file.  However, yes, it's pretty impossible to kickstart a system without 
getting some 32bit packages.  What I do here is just put a
"yum -y remove \*.i[36]86 in the %post section of the kickstart.  Voila 
-- no more 32bit packages.  And if there are no 32bit packages installed, 
it "shouldn't" pull any in at update time.

There may well be a yum plugin floating about to enforce this more 
strictly, but I haven't looked, to be honest...
