Asus EEE PC 1000HE power states : only C1 available

Hello,

I've just compiled FREEBSD-CURRENT on my new ASUS EEE PC 1000HE (Intel
ATOM powered) and everything seems to work well as of now (wireless
included), but I have a problem with CX power states.
The Intel Atom processor should have a lot of CX power states, but
only the C1 state is reported in oid "dev.cpu.0.cx_supported" .

I sent, as an attachment my dmesg log , sysctl -a output and acpidump
-t -d output.

I have an SMP kernel and it find and use my logical (Hyperthreading) cpu.

Is this a bug, a problem with SMP kernels (haven't tried UP kernel) or
simply this CPU is not yet supported by FREEBSD acpi?

Cheers,
Maggioni Marcello
