Arduino on the AVR Butterfly

I was wondering if anyone's gotten the arduino software stack running on the AVR butterfly: http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3146

I noticed that there was a port to avr-gcc of the butterfly application code (http://www.siwawi.arubi.uni-kl.de/avr_projects/#bf_app), but I was wondering if anyone had integrated it with very nice arduino software api? Or if that's even a sensible thing to ask.

I'm looking at a butterfly for an upcoming project, but I'd love to stay in the happy beautiful confines of the arduino software lib.

Thanks!

I looked at it a bit. The problem is that almost all of the IO pins on the CPU used on the butterfly are already dedicated to the IO functions on the butterfly board, so you wouldn't be able to use any of the arduino standard functions without having to deal with a lot of "gotchas." (I was hoping that with the larger CPU on the butterfly, there would be enough pins left over that weren't used for anything and could become the "arduino pins." But apparently not. Just the LCD uses up about 30 pins...)
