my dothan didn't work with cpufreq...

Hi,

I have a problem to use cpufreq with my Dothan based computer. During 
initialisation i get the following message:

speedstep-centrino: found unsupported CPU with Enhanced SpeedStep: send 
/proc/cpuinfo to Jeremy Fitzhardinge <jeremy@goop.org>

What I did. As i received no feedback I look inside the cpufreq 
sourcecode that throw the error and I tried to fixed it myself. I 
compared it with the content of my /proc/cpuinfo:

cpu family      : 6
model             : 13
model name   : Intel(R) Pentium(R) M processor 1.50GHz
stepping        : 6
cpu MHz         : 1500.834
cache size      : 64 KB

I located a correct cpu_id cpu_id_dothan_b0 but I wasn't able to locate 
were is it used (it  seems to differ from the banias  code).

In addition in the centrino_cpu_init_table(struct cpufreq_policy 
*policy), the loop that detect the processor failed as my processor 
string contains 1.50Ghz and not 1500Mhz (maybe an issue related to my 
Asus BIOS).

In fact, I could try to make a patch for making my processor accepted by 
the centrino checking code, but after this I ignore what will happend as 
no predefined tables frequency/voltage exists like with the Banias. Will 
it burn my computer :) or will it nicely use acpi/ich4 in some way ?
