Putting it in eeepc-laptop is probably easier. I'd recommend doing it
with cpufreq, but making sure that the transition latency is large
enough that ondemand won't try to mess with it. There's actually an
interesting question of what to do with making sure performance doesn't
bind and push you to a speed you don't want by default. I'll talk to
Dave about that.
