I made some noises at that time, and got a few replies from Lennart
about the problem.  From what I remember, the cs4236 chip is in some
"funny, intermediate" state when NetBSD starts running.

Lennart came up with something he referred to "too ugly to commit",
which was doing an inb(0x534) at the appropriate slot in the isapnp
code to have the chip decide which emulation it should provide.

> Was that ever successful?

After recently passing on the old message from Lennart, John Kohl
sent me the attached message, which I'm sure he'll forgive me for
forwarding.  I've not gotten around to trying this out on my office
machine (a Dell PC).

Note that the patch in the attached message is still a gross hack,
and this problem will hopefully be solved in some less intrusive
manner in the not too distant future.

That's what I got too when I tried to configure the wss isapnp
device.  At the moment I'm pretending that I have an ISA sb card in
my office machine (which is now some 900 kms away from me), and with
that at least playback works as it should.

In general the "not configured" means that there is no corresponding
driver in the kernel you are running.  In some cases (as here),
there is configuration data on hardware which can be read (e.g. PCI
vendor and product IDs), and the kernel is translating that for you
into textual information.

In this particular instance it means that you did not have the
pciide devices enabled in your kernel configuration file.  If you
want to be able to make use of the bus-master DMA properties of your
PCI IDE hardware (significantly reducing CPU overhead in I/O
operations), you need to use the pciide devices.  I don't remember
offhand if the above hardware supports bus-master DMA, although I
suspect it does.

I got my sound card working in wss mode (works better, too).

Here's my first patch.  I'm trying to refine it a bit...
