[patch][rfc] depend pcspkr on CONFIG_EMBEDDED

Hello.

As most of the problems with snd-pcsp
are now settled and the major distros
are starting to unblacklist it and use
instead of pcspkr:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=539767
I'd like to do that sneaky thing.
The major argument for keeping pcspkr
I've heard, was that it doesn't require
the entire ALSA stack, and in this
case I think it is usefull only with
CONFIG_EMBEDDED. Right now it is a common
situation when the both modules are
built, and whichever gets loaded first,
works.
So can something like the attached
patch be applied?

---
Depend pcspkr on CONFIG_EMBEDDED to reduce
the chances of both the pcspkr and snd-pcsp
being built together. pcspkr is good only
by not requiring ALSA; apart from that,
snd-pcsp does everything.
