What you see is probably a bug that slipped in 2.6.15-rc5:
It totally disables the use of cpufreq for passive cooling.
I already pointed Len to it and as this is really sever I am sure it
will be added before 2.6.15 is out if possible.
Also see Dirk Mueller's mail (12/21/2005):
Subject: make cpu_has_cpufreq() work
or the bug:
