Will try, but it is changing to 2200 MHz while I am doing the
CPU-intensive tasks (compilation of something big) and the debug
printf's are telling about 2200 MHz as well. Not so good benchmark,
but at least something.

I am just using the defaults for the -CURRENT. Can not verify
them now -- my -CURRENT is crashing with the modem link, so
I am either writing mails or doing the tests, sorry.

Yep, that was the constant 3Kbps. I do not understand the measured
values too.

Monday will reveal the things. Will post an update.

Thank you!
