I'd wander over and have a non-confrontational chat with the pilot when he/she lands. I've never met a pilot intending to cause a nuisance, and may be able to follow a different course to reduce the noise. You may even get a flight out of the visit if you are polite enough :-)
Do it before you're really hacked off and can't be polite.
Depending on where you are, it may be temporary while the Olympics close down lots of airspace.
