looks I was too hasty the last time. Actually this series breaks HDMI
output for me (or at least with 'simple_ondemand' governor, haven't
tried with performance yet).

I tried to run some simple application, but it hangs in uninterruptible
sleep immediately, probably before the first page flip. Going to check
this more thoroughly.

Maybe some parts of the hdmi subsystem don't like the lower clocks?

With best wishes,
Tobias
