Can't set CPU governor after resume

Fresh install of Arch. The CPU governor is always set to ondemand after resume.

/etc/conf.d/cpupower:

# Define CPUs governor
# valid governors: ondemand, performance, powersave, conservative, userspace.
governor='performance'

# Limit frequency range
# Valid suffixes: Hz, kHz (default), MHz, GHz, THz
#min_freq="2.25GHz"
#max_freq="3GHz"

# Specific frequency to be set.
# Requires userspace governor to be available and loaded.
#freq=

# 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=

# 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=

#  Sets a register on supported Intel processore which allows software to convey
# its policy for the relative importance of performance versus energy savings to
# the  processor. See man (1) CPUPOWER-SET for additional details.
#perf_bias=

# vim:set ts=2 sw=2 ft=sh et:

resume hook in /etc/pm/sleep.d/10misc:

 resume)
        rc.d restart cpupower
        ;;

/var/log/pm-suspend.log:

I should also note that starting the cpupower daemon in rc.conf still sets the governor to ondemand on boot.
