Guess I better wait then...

Maybe you're not seeing the same problem I'm seeing? Whenever I boot up,
I get the following:

ad1848/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996
ad1848: No ISAPnP cards found, trying standard ones...
opl3sa2: Activated ISA PnP card 0 (active=1)
opl3sa2: chipset version = 0x2
opl3sa2: Found OPL3-SA3 (YMF715 or YMF719)
opl3sa2: Search for a card at 0x880.
opl3sa2: Control I/O port 0x370 is not a YMF7xx chipset!
opl3sa2: There was a problem probing one  of the ISA PNP cards, continuing
opl3sa2: Control I/O port 0x370 is not a YMF7xx chipset!
opl3sa2: There was a problem probing one  of the ISA PNP cards, continuing
opl3sa2: Control I/O port 0x370 is not a YMF7xx chipset!
opl3sa2: There was a problem probing one  of the ISA PNP cards, continuing

and I end up loading the modules by hand... well, I've got an
/etc/modutils/opl3 file since about 2.4.5 or so which specified options
for the opl3sa2 and opl3 modules (I didn't think I needed opl3, but the
driver maintainer had it in his /usr/src/linux/Documentation/* file).

This setup works fine except that I'm missing those extra mixer
channels... and the sound doesn't seem as good as when I plug my diskman
into my computer speakers (so the problem isn't using better speakers
:-)
