I believe (and from my tests I think I am right) that /proc/config.gz is 
just the .config files used to compile the kernel, gziped. So ether a 
'zless /proc/config.gz' or 'gzip -cd /proc/config.gz | less' or what 
ever method you want to gunzip the file and read the contents, will give 
you an identical file to the .config used to compile the kernel. As far 
as I know it doesn't contain a kernel image.
