look in the distro tree : 
http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS ( eg, for the i386  )
the kernel-2.6.9-*.<i686|i586>.rpm are the ones used for the installer, 
each contain a .config file which will give you the config file used at 
build time for that kernel rpm.

Why do you need to rebuild the installer kernel ? doing DriverDisks for 
some piece of non-supported-by-default-hardware isnt hard.
