hi jeremy

i've found a pentium-m banias which reports "Mobile Genuine Intel(R)
processor       1400MHz" in /proc/cpuinfo.  this (strange?) signature
prevents speedstep-centrino.c from working properly.

the machine is a asus L4000R-series (L4510RBP) pentium-m/ati9100igp
notebook.

"Enhanced SpeedStep" works as advertised for this particular pentium-m
with the following trivial patch applied:

# diff -up arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c.default arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c

it seems that only the model_name is different for this CPU?

thias
