The basic wisdom about a kernel is to use as few pieces in it as
possible. If you can get away with stripping it down to bare minimum
then you have removed sections of low non-swappable memory from ever
loading. Optimize to your current CPU level. Maybe implement QoS and
firewalling so you can protect your system better plus get your RTP out
with priority. 

I can't comment on Fedora vs. RH9 versions of the kernel as I personally
won't ever run one unless I am hog tied to some special driver whose
creator pushes binary only packages against one of those pre made
kernels. I prefer the bone stock kernel.org sources, but that is just a
preference.
