That's a good question.  A note that including including this module
could potentially cause sound cards to be renumbered might be
reasonable, since I suspect most users (and most application
programs!) have been accustomed to only having one sound card, and so
building this module may cause sound cards to be renumbered in Kconfig
would at least be a start.

I know this wouldn't help users of distro kernels, but this would at
least be one way of warning distro maintainers to think twice about
enabling it as a module.  BTW, what *is* the utility of this card, and
how do you use it?  I haven't been able to figure out how to use it do
anything entertaining at all.  Any attempts to use it on my system
just lead to various confusing error messages.

Also, BTW, it might be nice to remove the following hunk of text from
drivers/sound/Kconfig:

	I'm told that even without a sound card, you can make your computer
	say more than an occasional beep, by programming the PC speaker.
	Kernel patches and supporting utilities to do that are in the pcsp
	package, available at <ftp://ftp.infradead.org/pub/pcsp/>.

What's there at the above URL is for the 2.2 and 2.4 kernels, and the
utilities at pcsnd-kit.tar.gz don't work (and didn't compile until I
futzed with them slightly).

So I'm still rather puzzled how to make the snd-pcsp actually do
anything useful, unless it simply doesn't work on my Thinkpad.  (Is it
normal that the sound volume levels reported by alsamixer can be muted
or unmounted, but always report 0, and can't be adjusted up?)
