I decided to use the src.rpm from FC5
http://rpmfind.net/linux/RPM/fedora/devel/x86_64/cpufreq-utils-0.4-1.1.21.x86_64.html
everything went very smoothly.
When I tried to rebuild powersave again I hit the same error as before. 
It seems you forgot to change the powersave.spec. Anyway, after replacing
%_prefix/lib/powersave
by
%_libdir/powersave

as danny kukawka suggested I got rebuild powersave, powersave-libs and 
powersave-devel rpms. After installing them I was wondering what to do 
next. obviously I was not to hoping this is the end of adventure yet.

thus here are some results:

1) the daemon didnt start after reboot.
there is a script  /etc/init.d/powersaved, however running

[~]$ sudo /sbin/chkconfig --add powersaved
service powersaved does not support chkconfig

does not help much, therefore you cannot see powersave daemon in 
system-config-services utility.

what I had to do is

#ln -s /etc/init.d/powersaved /etc/rc3.d/S92powersaved
#ln -s /etc/init.d/powersaved /etc/rc5.d/S92powersaved

in order to get it running at system start.
(would be nice to get this fixed)

2) but the last step apparently didn't help either
[~]$ cat /var/log/messages | grep powersave
Jan 29 00:29:45 localhost [powersave]: ERROR (PM_Interface:89) Haldaemon 
not running. Battery or ac adapter information will not be available.
Jan 29 00:29:45 localhost [powersave]: WARNING (ACPI_Interface:49) could 
not set battery alarm
Jan 29 00:29:45 localhost [powersave]: ERROR (MainLoop:59) Error setting 
up connection to DBus system bus. Aborting...


3) then I decided to run powersaved as root.

# /usr/sbin/powersaved -d
goes just fine with no output.
gkrellm-powersave works fine (I must point that since I'm using fluxbox 
then this is the only option for me instead of kpowersave). I can switch 
  between performance/powersave/dynamic modes, and battery indicator 
works as well. Also powersave [-xasbBSTr*] works fine and gives a nice 
output.

4) Thus I decided to try "suspend to ram"
but I got the following message:
suspend2ram failed on unloading 'ohci_hcd'. Trying to recover...

and nothing more after that, but apparently it managed to unload the NIC 
module, because it was not working.

I'm not sure what hardware is ohci_hcd module responsible for. lsmod 
does not tell much. It might be the firewire controller.

So considering all about I would like to:
- be able  run powersaved daemon in a regular way and not as root only 
(I suspect that this has something to do with access privileges, 
apparently there should be some group created, which is not there yet )
- be able to send the system into "suspend to ram" state.

thank you in advance
