You neglected to tell us which FreeBSD version you are running - but
on my -CURRENT system, the cx_usage and cx_supported sysctls are still
there:

$ sysctl -a | grep cx
hw.acpi.cpu.cx_lowest: C3
dev.cpu.0.cx_supported: C1/1 C2/1 C3/17
dev.cpu.0.cx_lowest: C3
dev.cpu.0.cx_usage: 95.09% 0.14% 4.76%
dev.cpu.1.cx_supported: C1/1 C2/1 C3/17
dev.cpu.1.cx_lowest: C3
dev.cpu.1.cx_usage: 0.00% 97.66% 2.33%

Mind you, this is with the in-tree USB stack.

Regards,
Brix
