List of chips the IDE can work with?

[system]

Is there a list of what chips that are able to work with the arduino IDE?

I know 168 and 328 flavors, and there is a attiny84 port of the IDE. Oh, The Sanguino with the 644. Mega 2560 of course

Any others? I know I'm missing something.

There are only a few modifications necessary for the ATmega324P:
