Load cpufreq.ko when powerd is enabled
100%
Description
Looks like we need to load cpufreq.ko when powerd is enabled, and some systems also need to change their timecounter (but there may not be any automated way to accommodate that)

What kind of hardware are you using?
I'm running it on my router (VIA CPU running a NanoBSD snapshot) and it loads without error, and does appear to be adjusting the CPU frequency properly:
dev.cpu.0.freq: 373 dev.cpu.0.freq_levels: 995/-1 870/-1 746/-1 621/-1 497/-1 373/-1 248/-1 124/-1
(run a few commands)
dev.cpu.0.freq: 497 dev.cpu.0.freq_levels: 995/-1 870/-1 746/-1 621/-1 497/-1 373/-1 248/-1 124/-1
Can you tell if cpufreq.ko is loaded? (run kldstat from a shell prompt)

I got that error the next time I booted my router, so it may still be an issue. I'll look into it.
Does the ALIX even support multiple frequencies? If you load cpufreq by hand do you get output similar to what I show above?

Closing this as the error given is due to ALIX not really supporting powerd with the default TSC timecounter, which is not the fault of cpufreq.ko which loads OK at boot time.
If we need some other mechanism to change timecounters (if that would even help) that would end up being a new feature and not really related to this ticket.
