Hm, is it possible to provide one cpufreqd.conf-2.4 for 2.4.x Kernels
and one cpufreqd-conf-2.6, which supports 2.6 Kernel Versions?

Maybe it would be useful to provide an Debconf Config. interface, which
is started during Installation and makes it possible to select an proper
Configuration file, ala:

	"These Kernel Versions where found on your system:"
		
		2.4.18 		[ ]
		2.6.0-test4 	[ ]

	"Please select which Kernel Version should be supported
	 by the cpufreqd Configuration File per default"..

(.. the Debconf Iface should provide detailed informations why the
user has to select the right configuration file ..)  

Based on the selection, the right configuration file is copied to /etc/
and the other Configurations are copied to /usr/share/doc/cpufreqd/
examples/cpufreqd.conf-2.6-example and so on ..

You can try to tweak the startup scripts to not start the Daemon
if the User selected an Configuration file which is not matching
the running Kernel. (so, if he selected an config file, which
supports 2.4 Kernels and runs 2.6x the deamon does not get started)

I hope i got it ;-)
