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,
