Hallo!
I already tried the epia1 patch for the 2.6.6 kernel, I even tried the acpi patch (acpi.sourceforge.net) for the 2.6.7 kernel, without getting the new kernel recognize the processor to have also a C2 state (saves about 25% power when idle) ...
What processor do You have (cat /proc/cpuinfo) and what does ACPI say (modprobe processor; cat /proc/acpi/processor/CPU0/power)?
Maybe something went wrong during the patching or I made something wrong in configuring the kernel?
Saluti!

I have a VIA C3 (Ezra) processor. It is very nice for "normal" applications, as it takes only a few watt.
Now: does anyone know how I can achieve full ACPI support for my processor in a more recent kernel than 2.4.20? In special I would like to use frequency scaling/throttling, as most of the time my small computer does nothing.
I also have a VIA C3 machine, installed kernel 2.6.6 on it. I have absolutely no knowledge of ACPI and all, but perhaps the following link will provide the information you need:
http://www3.sympatico.ca/howlettfamily/epia/epia_howto/index.html
According to section 8.1, it is possible to get frequency throttling to work, but with kernel 2.6.6 you need to patch the source and compile from scratch. I have done this, compiled the kernel 'the Debian way' with help from: http://www.desktop-linux.net/debkernel.htm ... and use the '.config' from the link supplied in section 11.1 from the first URL I wrote above.
Good luck,
