A colleague of mine looked into this some time ago as part of his PhD
thesis. This was pre-801.11n, so they were doing experiments on adding
aggregation to 802.11g by messing with the MTU. What they found was that
they actually got better results from just sending data when they had it
rather than waiting to see if more showed up.
