Unfortunately, this is just a hisorical problem that we have to live with. Yes, 
Atmel has improved its consistency on newer device families such as xmega and 
the UC3 for the AVR32. However, this doesn't help us with past device releases. 
:-( We just have to accept this fact and move on the best we can.

Would you be willing to describe in more detail about what you do to solve this 
problem? I think it would be good if we heard from others' experience.
