[Om2008.9] Using Freerunner as a digital audio player

The qtopia mediaserver takes ~35% cpu to play my max bitrate
VBR-encoded mp3's. I don't have mplayer installed and not /dev/dsp for
madplay so I cannot test with those.

For average tasks, the UI is still nicely responsive in these latest
testing builds. Anytime the load gets to 2, though, you start to get
audio cutting out. GTA02 is not a brute.

I actually have not tested audio interruption (i.e., incoming call) in
a while, but I have never had a problem with it.
