Having a config in /proc is a option in the kernel.  You just have to 
turn it on.  It is under the General setup as "Enable access to .config 
through /proc/config.gz".  I have mine here:

root@smoker / # ls -al /proc/config*
-r--r--r-- 1 root root 10060 2008-08-05 14:19 /proc/config.gz
root@smoker / #


It can prove helpful at times.
