I've got it working now, thank you very much. I had to apply kernel patch
first and then recompile kernel. RedHat 7.2 contains lspnp and, oddly enough,
man page for setpnp, but no setpnp binary. So I used lspnp to list PnP
assigned resources and I was able to see that resources for my
audio-controlled are disabled. So I had to download pcmcia-cs, compile it
(make all) and then install setpnp only (cd debug-tools; make install). Then I
used setpnp to turn on my audio controller (0e is number assigned to this
controller as listed by lspnp):
  setpnp 0e on
After that, cs4232 module is loading fine.

I hope PnP BIOS patch will be merged in kernel soon and RedHat will
incorporate setpnp into their version of pcmcia-cs package. It is always pain
when something that should be included by default is not included (especially
regarding kernel).

Now, while problem solved, still there are issues that I don't understand:
1. What could be disabling my audio-controller during Linux boot process (when
I list PnP resources by lspnp -b -v, everything is enabled)? If that matters,
I'm using GRUB boot loader.
2. Sndconfig is still (even after turning audio-controller on) reporting
"modprobe: Can't locate module sound-slot-0" error. I guess then I'll should
add manually appropriate lines to modules.conf for my audio-controller. So
what these lines should look like if kernel/OSS driver used?

Thanks.
