Why C3 state isn't entered?

Hello!
I've got Centrino notebook (specifically Asus M3700Np), and it doesn't
seem to enter C3 sleep state in any case.
Sample output from 'sysctl hw.acpi.cpu' (while working at battery):
hw.acpi.cpu.cx_supported: C1/0 C2/1 C3/101
hw.acpi.cpu.cx_lowest: C3
hw.acpi.cpu.cx_usage: 0.00% 100.00% 0.00%
So C3 is supported, is allowed but isn't entered according to cx_usage.
Why could it be so?
My system:
bash-2.05b$ uname -a
FreeBSD smira.mlab.cs.msu.su 6.0-CURRENT FreeBSD 6.0-CURRENT #1: Wed Oct

Thanks,
Andrey.
