Spot on. This turned out to be out of date but I didn't realize
that at first.

So true. I don't appear to need to blacklist anything so I took
out that directive and basically got back to where I was
previously.

	I then tried to see what would happen if I manually
inserted snd-cs4236 using modprobe. For the first time since July
15 of last year, I got back the cs4236 and set it to Card 0. The
usb card which I have been using as Card 0 can now be card 1 and
they are both present.

	If I reboot, however, Card 1 which is the usb card
automatically returns as it should but there is no Card 0 until I
manually run

modprobe snd-cs4236

at which time it and all necessary modules for it come back.

	This is obviously not right but proves it can work.

	I wonder if there is not a race condition going on? It
sure seems to have that smell to it.
