I have a sound card that is based on an OPTi 925 chip set and it is
PnP. This card has no jumpers so that it is impossible to manually set
irq, dma and port. Linux does not find the card (specific message: sb
compatible card not found at irq 7). How can I make Linux detect it?
I'm running kernel 2.0.1.

You have two problems: first the 2.0 kernel doesn't support the 925 (or
924) chip. Secondly it doesn't support plug n' play.
I solved this by moving a file called mad16.c from a 2.1 kernel (which
has support for the 925 chip) to 2.0.29 and initializing the card from
dos with DOS Intel Configuration Manager v1.45 (get it from
http://www.redhat.com/linux-info/pnp//other.html) before booting Linux
with loadlin.
