/* actually SetCpuFreq is used to determine if the system is in standby
this is an "elegant" hack, because:
* during a recording, cpu freq is kept "high", even if the box is sent to standby
* the "SetStandby" call is made even if a recording is running
On the TD, setting standby disables the frontend, so we must not do it
if a recording is running.
For now, the values in neutrino are hardcoded:
* f == 0 => max => not standby
* f == 50000000 => min => standby
