ATMEL Mega1284P evaluation board avalible

Would be cool if someone could come up with a core files needed to run this $29 puppy with the arduino IDE

It looks like the crystal is 11.0592 MHz (or something close; I'm having trouble reading the number). Is that the only issue? Modifying an existing core for the "odd" crystal frequency?

Is there a core available for the 1284P family? (isn't it just a big 644?)

Do you picture this core having built-in support for the gadgets?
