It turned out that cpufreq used acpi_perf instead of ichss, so it was not
acpi_sony related! Solution was to add hint.acpi_perf.0.disabled="1"
But now I have the problem that a regular user can't change the brightness:
akima:~>6: sysctl -w dev.acpi_sony.0.brightness=5
sysctl: dev.acpi_sony.0.brightness: Operation not permitted
Is there a tunable to allow regular users to write to dev. sysctls or even
better, a sysctl MIB security mask to assign "rights" to a specific MIB?
