I patched my kernel with Bruno's suggestion but that did not change anything. 
I guess from looking at it, I should get a Kernel Error Message 
with "notifying SMM bios failed" message. I will check the logs (It is on a 
seperate HDD for this same machine (need to keep my production machine up and 
clean). 

I have installed 2.6.17 and compiled with the cpufreq debug, and here is the 
portion of dmesg I am sure you are intrested in:

Bruno / J, 

What should I be looking for with the patched speedstep-centrino.c? Where 
would this message be? In my /var/log/messages or under another log file? 

Thanks for all your help?
