Thanks anyway.  Can you tell if processor C3 is enabled with a 2.6 kernel?

Also, I would like to receive the lspci -xxx -s0:0.0 for the northbridge,
and the same for all the function of the PIIX4 southbridge.

Even if you may think that it is irrelevant, I would like to receive
the output of speedstep-detect from
ftp://ftp.poupinou.org/cpufreq/speedstep-detect.tar.gz

because it dump the pm io registers of the PIIX4, regardless of the processor..

I think the trouble come from C3, just need to check some values.  If you
can, it may be usefull that you disable C3, with something like that:
