That is awesome, thanks!
I had to use tilib instead of rf2500, but after that it seemed to work. Weirdly the first few times that I unplugged the board and plugged it back in the program seemed to get lost. Then the 4th or 5th time I loaded the program it seemed to stick.
I'll probably pick up a handful of those arduino clones, and maybe a few of the atmega chips so I can just program them and use them without the board, I've just had this board laying around so long that I really wanted to see it given a use.
