Any "Centrino" labeled system has a Pentium-M CPU 9one of about three different cores, I think, although I don't know if the Sonoma core is shipping in volume. It's not a P4-M or a P3-M, although it is generally believed to be closer in design to a P3-M. As far as power management goes, the framework will be in 5.4, but the drivers (ESST for a P-M) have not been imported nor has powerd. If you want to play with them, they can be pulled from HEAD and built on a 5-Stable system. I suspect that Nate Lawson will MFC them to 5-Stable pretty quickly after 5.4 is released and RELENG_5 is re-opened. The ICH SpeedStep support in Current is working quite well on my laptop, but I am not happy with powerd just yet. (I have been trying different tweaks in the code this morning.) I understand the the Enhanced SpeedStep for P-Ms is also working well. Since the power management is closely tied to ACPI, it's discussed on acpi@ quite a bit and also on mobile@. -- R.
