Hi Stefan,

you didn't include me in your answer, hence the late reply...

That's an interesting point. However, that would be a different discussion. I
wouldn't mind if the 144MHz would be removed - my point was just that if it's 
supposed to be a common setting, it should work on all boards. I posted a patch
today to fix this. [1] That might be a good place to discuss whether this
setting should be removed entirely.

Regards,

Timo
