Thanks :) Feedback is very helpful.

Hrm. The only cards that would automagically match the logical device ids
there were Creative Labs cards. No other vendors have CTL as their ISAPnP
vendor id. And we know what all the ISAPnP ids are for these Creative Labs
and ESS cards, so I don't see the problem. Besides, I am willing to handle
a few "My card isn't autodetected anymore, what happened?" bug reports to
l-k for a code cleanup. Fixing these is a simple matter of adding entries
to sb_isapnp_list.

I thought that if the user went through all the trouble of messing with
/proc/isapnp that he could use isapnp=0 and enter in the paramaters with
module options, as before. But I also like the multiple detection scheme.
I had stopped working on it after not hearing back from Alan about the
idea.

Ok, I'll rework the multiple card detection back in, and leave your
"already active" behavior alone. Then I'll repost and have another round
of comments and testing.
