A patch to support centrino 1GHz

A patch to support centrino 1GHz

I recently bought a new laptop(Panasonic CF-T2) with Pentium M 1GHz.
I installed RedHat9.0 and upgraded the kernel to 2.4.22 with the latest 
CPUFreq patches for 2.4.
Then I found that speedstep-centrino.o failed to be loaded with the 
following error message,

speedstep-centrino: no support for CPU model "Intel(R) Pentium(R) M 
processor 1000MHz": send /proc/cpuinfo to Jeremy Fitzhardinge 
<jeremy@goop.org>

So I added Pentium M 1GHz model entry in speedstep-centrino.c (See the 
patch attached).
This works fine with my laptop.
I looked up the frequency-voltage table for the processor in the revised 
version of Pentium M data sheet, 252612-002.pdf, from Intel.

Done. Linus hasn't been taking things like PCI ID updates and the likes
for the last few weeks however, so this may have to wait until post 2.6.0
In the meantime, it'll sit in the cpufreq tree waiting to be pulled.
