[Solved] Cpupower: some settings not supported?

Question

Hey all,
I just installed cpupower instead of cpufrequtils and I think I got it up and running (module acpi-cpufreq, daemon cpupower in /etc/rc.conf and edited /etc/conf.d/cpupower).
I also tried the newer settings mc_scheduler and smp_scheduler as seen below in the code part. However, when I then restart the daemon, I get Error setting sched-mc not supported. Why? I own an Intel Core i5 430M and I thought that cpupower was supposed to be more compatible with it than cpufrequtils, e.g. support more of its features.
# Utilizes cores in one processor package/socket first before processes are
# scheduled to other processor packages/sockets.
# See man (1) CPUPOWER-SET for additional details.
#mc_scheduler=1
# Utilizes thread siblings of one processor core first before processes are
# scheduled to other cores. See man (1) CPUPOWER-SET for additional details.
#smp_scheduler=1

Yes that is the "smp scheduler", the config file uses the wrong abbreviation there i think. It works though:
$ cat /etc/rc.d/cpupower
params+=(${smp_scheduler:+-s $smp_scheduler})
$ man cpupower set | grep smt
--sched-smt, -s [ VAL ]
