Yes the patch is still needed.  Setting the MTU smaller than a normal packet 
will cause the frame to be IP fragmented.  So you should be seeing at least 2 
packets on the wire being IP fragments.  Use wireshark (or something similar) 
to make sure those packets make it to on to the wire.

Cheers,
John
