Maybe RH modifies the oldconfig target.  I know SuSE offers another
option which can read the config of a running kernel.  It's called 'make
cloneconfig' and works as long as the kernel is built with an option to
generate a compressed copy of the config in the compiled kernel
(/proc/config.gz.)  As far as I know this is SuSE specific though, so
you'll need to use their kernel RPMs for this to work.
