Summary:                    ISA cards (opl3sa2 in particular) are not detected
properly on 2.6 kernels
Description: 
When brute-force detecting my OPL3SA2 card, the IRQ and DMA1/DMA2 settings
are incorrectly detected by alsaconf from alsa-utils. For example, the
default BIOS settings are IRQ=11, DMA1=0, DMA2=1, but alsaconf detects
IRQ=5, DMA1=1, DMA2=0. No matter the BIOS settings, alsaconf always
detects those settings (IRQ=5, DMA1=1, DMA2=0). If I set the BIOS settings
to that, then the card will make sound (after touching the mixer while
playing audio).

According to perex (author of the opl3sa2 driver):

"The alsaconf tries to gather free resources (irq/dma/ports) from the
/proc filesystem. It might be extended to gather this information also
from /sys filesystem."

I tried adding that line and it did not immediately work. I tried using
alsaconf and modprobe snd_opl3sa2 and neither worked. I may have
unintentionally borked my machine though by removing /lib/modules/`uname
-r`/kernel/sound after I was getting errors trying to insert the new
module.

When I get home later today, I'll try rebooting and reinstalling ALSA
1.0.9 completely with all above patches and added lines. If that still
doesn't work, I could try downloading from CVS and let you know how that
goes, presuming all above patches are applied there.

I'm starting to think that it might work better/faster if I just make you
an account on my machine and let you poke and prod the hardware and try
stuff. Would that work [better]? I'm pretty sure that I'm doing everything
correctly in patching and testing, but in the case that I'm not, I don't
want you to have to keep writing patches and code and being bothered with
this when there is a PEBKAC on this end.

Another thing I've noticed and figured I'd add is the following message
from dmesg:

PnPBIOS: Disabled by ACPI PNP

I've tried alsaconf and modprobe for installing the module with ACPI off
and this PnPBIOS on and ACPI on and PnPBIOS off and I don't think there's
a difference.

However, if this will make a difference, well, now you know.
