turning off EDNS0

I am running bind version "BIND 9.2.2-P1" and I notice that my query 
times are very long.  When I run Ethereal to see why, I see that initial 
queries are sending the OPT pseudo RR.  Almost every nameserver out 
there responds to this with RCODE "format error" and then bind issues 
another query without this extension.

This is really increasing my relsoving time.  I would really like to 
disable this, but apparently I can only do this on a per server basis.

First, I would like to know how to disable this globally (hopefully 
without recompililng).  But something makes me think this is not what I 
want to do.  I just can't believe that ISC would release BIND9 
configured by default to double resolving times.  Am I doing something
