Ondemand/Conservative not working with 2.6.18

[S.ÃaÄlar Onur]

Hi;

With kernel 2.6.18 "ondemand" and "conservative" governors are not working 
with Sony Vaio FS-215B laptop, no frequency scaling or anything else :) 
occurs while system is %100 idle or at any workload using these governors, 
but setting "performance" governor changes to 1733 Mhz and "powersave" 
changes to 800 Mhz as expected. They all works without a problem with 
2.6.16.x, system information below;
