I've had complaint, (and noticed myself) that conservative and ondemand
often take a few hundred ms to "ramp up" to a suitable frequency.
Ordinarily this isn't a problem, but with my dual 1.6Ghz laptop idling
down to 1Ghz, clicking 'Applications' doesn't feel as "snappy" as it
should.

I guess it's a difficult balance between latency and smoothing to avoid
changing the frequency too often.
