>>> It turned out that even though doing yum install of these packages causes the pulseaudio rpms to be installed as dependencies, someone on this list clued me that some of the media packages have a config file (such as mplayer) where you set up the audio output device to something other than pulseaudio. Since I have set it to alsa, I no longer have the problem I reported: namely that pulseaudio daemon was chewing up to 35% of cpu wen audio was playing.

As I had  indicated in my original post, my only problem was load factor.
Pulseaudio was taking upto 35% of my 2.2 GHz Athlon cpu. That's a gigantic load factor!! When combined with how firefox often consumes upto 98% of cpu, I am left with a dead system. There was not much I could do about firefox (3.5) other than perhaps stop using it. But I wanted to do away with pulseaudio, because I know I did not need it in my previous fedora installation (currently I am on F11).
