I don't really know a lot about ACPI, so nothing sticks out.  You might
want to try the cpufreq list (which I'm cc: on the reply), and see if
someone there can help.  The full output of dmesg would be useful
though.

Hi,

You already got speedstep up and running using the ACPI cpufreq driver:

> > acpi 4684 0 - Live 0xe09cc000

you load it _before_ speedstep-centrino, even. disabling it should allow you
to load the (faster) speedstep-centrino module...

... with which you should get 10uS latencies instead of 100 uS.

Ah, thanks Dominik, that was an easy fix.

I incorrectly assumed that that was a helper for the cpu specific 
module. I was going by the Gentoo Power management guide 
<http://www.gentoo.org/doc/en/power-management-guide.xml> which says to 
configure:

<M> ACPI Processor P-States driver

and

<*> CPUFreq driver for your processor

It goes on to say...

"Compile your kernel, make sure the right modules get loaded at startup 
and boot into your new ACPI-enabled kernel." They didn't explain what 
the "right modules" are though. My bad.
