Adding other boards to the Arduino IDE

was able to get hold of the Arduino-Tiny files and add those processors to my Arduino 1.0 files.

What i am wonderring about is how to add another processor/board to the IDE. I would like to play with a ATMega324 (all those I/O pins...) but would like some document that would outline the process.

While I could do all the work using WinAVR or AVR Studio 4 (5 is too slow...) I like using the Arduino IDE and it provides the level of programming that I need.

Thanks

Maniacbug has a blog where he seems to have the similar '1284 working. Do a search for that.
