Starting powernowd: required sysfs objects not found!

[fabrice régnier <regnier.fab@free.fr>]

Hi all;)

This title is what i get in boot.log when i try to start powernowd. 
However, i think i have the sysfs since:

FR-PORT:~# mount | grep sysfs
sysfs on /sys type sysfs (rw)

FR-PORT:/boot# grep SYSFS config-2.6.15
CONFIG_SYSFS=y

FR-PORT:/boot# grep FREQ config-2.6.15
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=m
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
CONFIG_X86_ACPI_CPUFREQ=m
# CONFIG_X86_CPUFREQ_NFORCE2 is not set
CONFIG_X86_ACPI_CPUFREQ_PROC_INTF=y

Did i choose something wrong in the kernel ?

When i was running a 2.6.12, it was working perfect.

any idea ?
