Something I have been complaining about for years (won't fix). /etc/rc5.d 
has a link called S01ondemand, The README says:

"To disable a service in this runlevel, rename its script in this
directory so that the new name begins with a 'K' and a two-digit
number, and run 'update-rc.d script defaults' to reorder the scripts
according to dependencies."

So rename S01ondemand to K01ondemand and run (sudo) update-rc.d script 
defaults. That script has a 60 second delay in it (why?). If you have 
installed cpufrequtils there should be a file called S03cpufrequtils in 
that directory and look in /etc/default/ for cpufrequtils in there which 
should have 1 line

All done... you don't need a custom script or anything.
