I recompiled the kernel and hard coded irq 11 to card->irq in trident.c.
Then the sound card works. My notebook could now play sound. But it
generates strange repeating beeps in X-windows, if the event sound is
turned on. I am still troubleshooting it.. Anyway, now I got my notebook
run fairly good with 1024x768 X-windows, with network card and sound
card work as well. My friends are all surprised when they see my
notebook running Linux.
