I am getting really disappointed and annoyed trying to obtain
low latency. I have been losing so much time by now, and it
still doesn't work as I expected.

I now have kernel 2.4.14 with Andrew Mortons LL patch, configured
and activated thorugh sysctl, compiled for 386 (even though I have
an AMD Athlon 700), and I ran hdparm (indeed, I forgot to do that
the last time)

You can see my results at 193.145.55.36/latencytest

These results finally look good. However, when I try the use the alsa
latency test, the results are still far from what I expect.

./latency -m 256 -M 256 -r 44100 -t 1 -p

exits immediatly with an XRUN.

./latency -m 512 -M 512 -r 44100 -t 1 -p

sometimes works for a while before XRUN.

./latency -m 1024 -M 1024 -r 44100 -t 1 -p

seems to works well, but obviously this is not as good as what the
latencytest indicates.

A part from that (and I don't know exactly with what kernel
version or alsa CVS update this started, but it was not like this
before), alsa I/O is giving me weird distortion (knispering sound,
like a dusty vinyl record)!!!!! arecord -r 44100 -f S16_LE | aplay 
does not seem to have this problem.
