If so, then bsdinstall should stop offering powerd as a service during
installation (regardless of whethter in real or virtual env). 

It can discover this condition with checking for lack of
sysctl -a | grep dev.cpu.0.freq
sysctl -a | grep dev.cpu.0.freq_levels
in /usr/libexec/bsdinstall/services,

exactly as it does with
     if (sysctlnametomib("dev.cpu.0.freq", freq_mib, &len))
       err(1, "lookup freq");
       ...
     if (sysctlnametomib("dev.cpu.0.freq_levels", levels_mib, &len))
       err(1, "lookup freq_levels");
in /usr/sbin/powerd (via /etc/rc.d/powerd) - see powerd.c.
