You must have missed the followup that I had been in error and
the patch was still required.My working system includes only:
device         pcm0    at isa? port 0x52c irq 5 drq 1 flags 0x10

It does NOT include "options PNPBIOS" or "device csa".

The snippet of the dmesg indicates that the kernel was not built with
the patch to /sys/conf/files.

#!/bin/sh
perl -pi.orig -e "s@(dev/sound/pci/csa.c\s+optional pcm)@#\1@g;s@(csapcm.c\s+optional) pcm@\1 csa pcm@g" /sys/conf/files
diff -u /sys/conf/files.orig /sys/conf/files

The perl command above will do the patch and print a diff. It should
comment out one line and add "csa" to the next line. After running
this, rebuild the kernel 
cd /usr/src; make kernel KERNCONF=Your_Kernel_Conf

A reboot should show a clean probe line for pcm0 and no csa0.
