speedstep-centrino: ENODEV

[Jiri Slaby <jirislaby@gmail.com>]

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,
