nForce2 board, nVidia bin driver 5341 with ALSA sound driver snd_intel8x0. 
No sound daemon under my Fedora GNOME Desktop running. Online with DSL 
connection.
Ive tested it again, no chance with 2.6.5 only with rc3, switching back 
and it runs fine. ALSA changes? Or in the net code? To get sound in the 
game I do this:

echo "et.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
echo "et.x86 0 0 disable" > /proc/asound/card0/pcm0c/oss


The related part (i hope) of strace:
