Okay, I tried the 1.3.64 Kernel, and my soundcard works great! (a
Logitech Soundman Wave) both the low and high dma are recognized, the
midi sounds awesome, and thihngs copied to /dev/audio sound good.
And, finally both the left and the right channels work properly on my
systems.
Only one problem....
/dev/dsp doesn't work at all...
I either get an "Error opening audio-device" or a "Invalid audio buffer
size" I set the buffer size as recommended to 65536, and I have tried
128k, 32k, 8k, and 4k buffers using the dma_buffsize=???? when
installing the module.
Anyone have any ideas on this one?

I also have problems with ps -v giving a floating exception, no idea on
this one.
