It's not feasible unless you have a way of making various older CPUs transition faster. Ondemand on longhaul,powernow-k6,longrun, elanfreq, as well as lots of non-x86 implementations is just not a feasible option. However.. conservative might be. I'd still like to see conservative folded into ondemand sometime, and just be a module param. Dave -- http://www.codemonkey.org.uk
