IMHO, I'd say header pins are the way to go. I installed mine on a 1.0 board with very little soldering experience. Just be patient, go slow, and remember you don't need HUGE globs of solder. Also, for D0 - install a lead with a connector at the end. Don't have to worry about re-soldering if you buy a new chip.
Just did my second install with a chameleon... Header pin, connector for D0, Power and Eject, and a connector to a switch for A15. In all the install took me no more than an hour from start to finish.
If you have filled LPC points, just grab some desoldering braid - about 2 minutes of work clears them right out.
Martha Stewart Says: Make sure you have a decent soldering iron with a small tapered tip installed. Could get a solder sucker, but personally I think braid is just as simple and works better on these small points. It's a good thing.
