opl3sa2

I have a yamaha ISA sound card that uses the opl3sa2 module. This card is (still!) operational. The module in 2.4.x works fine. I haven't attempted to update to alsa and probably won't anytime soon. Everything works fine in 2.6.0 save this one module. Here is the relevant dmesg info..

Thanks for any help you can provide.
