Get .config from installed kernel?

[Kendall Shaw <queshaw@pacbell.net>]

Hi,

I have kernel 2.2.16 installed which I never compiled from source, and I 
want to add a kernel module to support my sound card. Is there a way for me 
to generate the .config that matches my installed kernel so that I can 
easily recompile the kernel as it is, but with support for my sound card? 
Or, with the 2.2.16 source, is there an easy way for me to simply compile 
the sound card support as modules and install them? Or rather, what is the 
quickest route to adding support for my sound card?
