If the option "store config in /proc"(or something like this) was 
enabled when the kernel was compiled, then you can pull the config with 
a command similar to this:
zcat /proc/config.gz > /usr/src/linux/.config
(assuming that you already unpacked the source of the new kernel)

I don't know if Fedora's kernel has this option enabled.
