Not sure about the overridemtu setting, but the connection-specific 'mtu' 
setting was ignored in 2.6.33. This was fixed in 2.6.34. I'd suggest 
upgrading to 2.6.34 before trying anything else.

As a workaround, with 2.6.34 you should be able to use the 'mtu' setting 
instead of 'overridemtu', if there really is a problem with overridemtu.
