Comment 69 for bug 370173

Hint: on "your" machine.

And it basically validates my points. You machine is not capable of
running Ubuntu without hacks, meaning your machine + Linux newbie =
Ubuntu does not work.

In my case the workaround is to use an older kernel. Not cool, but
workable. Although something in the system (and I have no idea what)
seems to limit which frequencies I'm capable to enable via cpufreq-set.
(might be as well the hardware that disable higher frequencies because
it is feeling "hot")
