You need to enable CONFIG_DEBUG_KERNEL _and_ CONFIG_TIMER_STATS
Then, yous should be able to grab timer statistics with:
echo 1 > /proc/timer_stats
cat /proc/timer_stats

Thanks a lot!
I was able to compile and to execute powertop on top of a sh4 processor :)
However, after starting, it shows me the following message :
--------8<--------------------------------------8<---------------------------------------------------------
No detailed statistics available; please enable the CONFIG_TIMER_STATS
kernel option
This option is located in the Kernel Debugging section of menuconfig
(which is CONFIG_DEBUG_KERNEL=y in the config file)
Note: this is only available in 2.6.21 and later kernels
--------8<--------------------------------------8<---------------------------------------------------------
I've recompiled my kernel updating the variable CONFIG_DEBUG_KERNEL,
but powertop continues showing me the same message.
For information, an uname -a gives:
Linux board-idtv 2.6.23.17_stm23_A18B-IDTV7109_7109-STSDK #1 PREEMPT
Wed Nov 25 15:53:15 CET 2009 sh4 unknown unknown GNU/Linux
Apparently, I'm using a supported version of kernel.
Thanks ahead of help.
Regards,
Carlos Prada.

You could also use
/-lncurses
instead of
//-lncursesw
