Yes, sure. If you use "pacat" you can play audio with almost zero CPU usage, because it is one of the few clients that actually asks for sensible latency (2s), which allows us to minimize the wakeup intervals to less than a second.

Just test it on Fedora 10
CPU usage of pulseuadio is above 3% when using pacat
CPU usage of pulseaudio is below 2% when using aplay
CPU usage of pulseaudio is below 3% when using paplay
the test audio is stereo 44100Hz pcm wav
Do you have any figures on Fedora 12 or 13 ?
