Hi,

I compiled the 2.6.0 kernel (released on Dec. 18, downloaded from 
kernel.org) with the options enabled for userspace cpufreq.. the 
documentation says that sysfs will be used however I do not have any 
such device in /proc/sys/ or in /. I enabled the /proc/cpufreq so I 
do see a /proc/cpufreq but nothing similar to 
/sys/devices/system/cpu/cpu0/cpufreq/ as mentioned in the kernel 
documentation which also says that the sysfs devices will be created 
automatically. Here's what my /proc/sys/ looks like:

root@variance:~# ls /proc/sys
abi/  debug/  dev/  fs/  kernel/  net/  proc/  sunrpc/  vm/

Below is the relevant config options in the kernel (the default on 
boot is set to userspace). Please let me know if I'm missing 
something and if there's some way to get the cpufreq working with sysfs.

Thanks,
nirmal
