I cannot help with FC kernels. Fedora packs a lot of custom hacks into there
kernel, if you build one your self it my not work the first time. If you
want to build your own kernel for Fedora I suggest you install on a practice
system first and then install all the kernel development tools that come
with Fedora. Once you have your custom kernel do not install any kernel
updates, it would undo your RAM fix.
I like to build vanilla kernels directly from kernel.org and use the CLI
tools. The option you need is CONFIG_HIGHMEM64G and if you use the make
menuconfig command like I do then you will find the option under Processor
Type And Features -> High Memory Support
This is a general list of commands I run
make mrproper
cp /boot/config-`uname -r` ./
make menuconfig
make dep
make bzImage
make modules
make modules_install
make install
vi /etc/lilo.conf
lilo
Fedora uses Grub not lilo. I find Grub to be far to limited. You should
expect problems because of selinux hacks in Fedora, get someone else to help
with that.
If you feel like you are not up to the challenge of building your own kernel
and this is a production system then I advise you to hire someone to build
the kernel for you or assist you with it. You may do will to poke around the
Fedora support forums, someone my already have a high mem kernel built.

You need music, music needs you; but the RIAA we'd all be better off
