I cannot find an answer to my problem. Sound was always working ok in
2.2.x and 2.4.1 kernels. But now the opl3sa2 module won't load anymore.
First I got the messages:

opl3sa2: No cards found
opl3sa2: 0 PnP card(s) found.

The I added isapnp=0 to the options line in /etc/modules.conf and then I

opl3sa2: Control I/O port 0x0 not free
It seems that the io address is not correctly passed to the module?!

The relevant lines from /etc/modules.conf are:

alias sound-slot-0 opl3sa2
alias sound-service-0-0 opl3sa2
alias midi opl3
options opl3 io=0x388
options opl3sa2 mss_io=0x530 irq=5 dma=1 dma2=0 mpu_io=0x330 io=0x370

Any idea???
