Do you have a /boot/config-xxx file? That tells all. If you don't have a 
config file, you're SOL. It should be there, all my Fedoras have one.

The 2.6 kernel was supposed to include the ability to query itself for 
compiled options, but as far as I know it has not been implemented in any 
useful way.
