Re: Re: speedstep-centrino does not load on an Intel(R) Pentium(R) M processor 1.70 GHz

[Thomas Tuttle <thinkinginbinary@gmail.com>]

If it is compiled in to the kernel, I get the "Found unsupported
CPU..." message.
If it is a module with the original code or with the patch you gave
me, I get "No support for CPU model...email [you]".
If I make a module with the full replacement for speedstep-centrino.c
you gave me, I get "No table support for CPU model".

I'm not sure why, but it doesn't seem to be able to retrieve the
frequency/voltage tables from the BIOS, no matter how I compile it.

Are there any tests I can run to just display the tables or see if
they can be read?
