have a new Lenovo Yoga ultrabook  and want to ruin LInux on.  I have been
through 3 or 4.  So I thought, "Let's try Fedora again."

i7 Mobile processor that touts a high CPU freq, but this is only in a
"turbo" mode.  Other distros have picked up at least four, on this same
machine.  What are the limitations I am facing here?  Kernel, modules, or
the inavailability of certain packages, like Jupiter, which I am starting
to like quite a lot?

the things it touted to fix have been incorporated upstream. The only

And you shouldn't be messing up with tools like cpufreq unless you know
what you are doing.
