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?

What messages do appear in the dmesg output? Is it "no support for > CPU model ...", "no table support for CPU model ..." or "found > unsupported CPU with Enhanced SpeedStep: ...".
