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
--- arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c.default 2004-08-19 19:53:59.000000000 +0200
+++ arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c 2004-08-19 20:49:06.000000000 +0200

+ .model_name = "Mobile Genuine Intel(R) processor " name "MHz", \

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