Louis Lagendijk responed to this issue a few days ago.  As I had just 
been searching on this I will go over what I did.

Basically, the /etc/cpuspeed.conf file needs to point to the correct 
module in the .../cpufreq/ folder.

Edit /etc/cpuspeed.conf so that the DRIVER line points to the correct one.

My machines that we affected by this issue are P4 HT 2.8 Intel.

My driver line now reads:

If yours is similar that should do it.
