Great. I recall running into this in the old port-from-1.x stack,  
where I had a #ifdef depending on whether it was micaz or telosb in  
the FIFOP code. I think there's just something weird with how the  
atm128 behaves.

I'll test this along with the beta2-candidate and (hopefully) check  
it in for the final beta2 RPM.
