Centrino question

Hi there,

I'm wondering if all Pentium M processor support C1 C2 and C3 ?
Because I have a Sony Vaio Z1 with a Pentium M 1.7ghz and linux only detects C1
and C2. I have a friend who has a Toshiba Tecra with a Pentium M 1.4ghz and it
supports C3.
I have heard that even C3 and C4 are supported by Centrinos.
I'm using kernel 2.6.6-rc3.
Is there a logical answer why the kernel does only detect C1 and C3 ?
Thanks

Cyril
