Many thanks for the information. Just after boot the file contains just
one line with descriptive information. After loading the module there
are in addition numerical values as described and I can change them as
described.

But: I'm wondering, that in lsmod speedstep-centrino is still
categorized as "unused" (normally there are references to other modules
or nothing at all). And if I switch the freq. to lowest
(echo -n "0:0:0:powersave") the file is changed and contains 600000 as
lowest and as hightest value with policy powersave, but e.g. in Kde
SysMon the freq. of the cpu doesn't change.


Thanks
