How about acpi-cpufreq? Does it work?
How did you mean this, speedstep-centrino (which can also control voltage) is
one of acpi-cpufreq drivers, isn't it?
Thanks,

Subject: speedstep-centrino: ENODEV
Hi!
How is it possible to find out whether or not
speedstep-centrino is supported. I
have
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.60GHz
stepping : 6
cpu MHz : 1600.149
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 apic sep mtrr
pge mca cmov pat
clflush dts acpi mmx fxsr sse sse2 ss tm pbe est tm2
bogomips : 3201.52
processor, but speedstep-centrino returns ENODEV because of
lack of _PCT et al
entries in DSDT (http://www.fi.muni.cz/~xslaby/sklad/adump).
It is possible to
hard-code that values to speedstep-centrino as for banias cpus
or use corrected
DSDT that will contain _PCT, _PSS and _PPC, but where may I
obtain these values?
This is Asus M6R notebook, some DSDT parts of this piece of HW
are really ugly
(problems with acpi some time ago).
I may use p4-clockmod (and it points me to speedstep-centrino
module), but if I
am correct, it doesn't save battery life?
regards,
