I and also other people had some patches to move the time stamp measuring into the socket. This way the time stamping didn't need to be enabled on all packets, only on those that actually end up at a socket that requires the time stamp.
Unfortunately DaveM didn't like it because some bank wanted different semantics, see the discussion in http://thread.gmane.org/gmane.linux.network/91679
Perhaps you can find out which bank it was and send them a bill for your CPU time ;-)
