Not according to lsmod. Loading it manually gives:
modprobe -vv powernow-k8
insmod /lib/modules/3.2.0-2-amd64/kernel/drivers/cpufreq/powernow-k8.ko
libkmod: INFO ../libkmod/libkmod-module.c:829 kmod_module_insert_module: Failed to insert module '/lib/modules/3.2.0-2-amd64/kernel/drivers/cpufreq/powernow-k8.ko': No such device
ERROR: could not insert 'powernow_k8': No such device
libkmod: INFO ../libkmod/libkmod.c:319 kmod_unref: context 0x7f9a84800210 released
It could be that something changed, but with kernel < 3.0 it worked!?
