Decoding of mp3 (and/or other media) with FP routines is extremely
slow on systems w/o fp processor. No matter is it "soft-float" or
"kernel-trap emulator". Both cases it is the emulator.(but SF is a
litthe faster because it has no "trap" overhead).

I used mplayed with libmad (libmad uses only integer ops to decode
mp3). It consumes about 10-15% of cpu time (au1200) to play mp3 file.
