hi ulf!

thank you for confirming this. i am actually searching for a solution which 
will get it right automatically when you select a profile. i'll send in a 
patch soon.

there are other differences between the boards, e.g. there could be different 
kernel configurations (optimizations) for different profiles. do we need to 
care about these?

best greetings,
