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?

thanks,
