No dev.cpu.0.freq on Gigabyte Z87X-UD5H with Intel Core i5-4670

I have no dev.cpu.0.freq syscontrol on my new system with 9.1-RELEASE or 
9-STABLE. I took the hard drive from my old system with a custm made 
FreeBSD 9.0 i386 kernel without SMP. The dev.cpu.0.freq syscontrol was 
there. Then I installed FreeBSD amd64 and it is gone, whether I use a 
GENERICS kernel or a custom made one. What can I do to bring it back in 
64bit mode?
