I'm not trying to program it, it's programming itself, flipping from 1
to 0.  The only problem this is causing me is that I have a script that
serializes the boards and it's halting on the error returned by AvrDude.
I've fixed this by changing the efuse to 0xF4 to match what the 1280
returns on verify, the problem with that fix is if Atmel decides to use
bit3 for something in future versions of the 1280 it could turn into a
very hard to find bug.

I'll report this to Atmel.
