Strange, I get no freq info in dev.cpu on a TP X31.
load cpufreq only:
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
dev.cpu.0.%desc: ACPI CPU (3 Cx states)
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU_
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.est.0.%desc: Enhanced SpeedStep Frequency Control
dev.est.0.%driver: est
dev.est.0.%parent: cpu0
load cpufreq and acpi_freq
acpi_perf0: <ACPI CPU Frequency Control> on cpu0
acpi_throttle0: <ACPI CPU Throttling> on cpu0
acpi_throttle0: P_CNT from P_BLK 0x1010
and
dev.cpu.0.freq: -1
