Just had to get the preliminaries out of the way and warn others that
this is something that can seriously mess the system if you get it
wrong.

Linux kernels can generate a replica of the config file used to compile
that kernel in the first place, and it is often in the same directory
as the kernel used to boot.  Keep in mind that I do not have a YDL here
for referral, so these are just some generic instructions.

The first thing I would look for is the directory where the boot kernel
is, usually /boot.  In this directory you will find one or more kernels
at least.  Kernels are often named vmlinuz-some_version, or
vmlinux-some_version.  The matching config file will be called
config-some_version.  In there is all the CONFIG_* values you want to
know about.

If that is of no help, you can read the kernel documentation from the
source package (README) about "make oldconfig" which should extract the
config info from your current kernel ready for you to tweak it and
recompile it.  You can grab this from the YDL.net server, it will be
called kernel-some_version.src.rpm.  There are several options for how
to configure the kernel, and instructions on how to build that kernel
in that README.

Good luck.  Document what works for you so that others can follow in
your foot steps.
