It looks like one can disable EDNS on a per-server basis; would it make 
sense to do this for all Akamai servers and hope they don't change often, 
or can/should it be done globally?

Also, would that explain why the problem goes away when I force a cname 
lookup?

My workstation is running 9.2.0 from the Mandrake RPMs.  The servers are 
all running 8.3.3:
