My kernel rebuilds:

1. Redhat Kernel Sources
# rpm -i  kernel-source-<version>src.rpm
# cd /usr/src/linux-<version>
# cp /boot/config-<oldversion> ./.config
# <edit> Makefile
Change extra version to the kernel version of your choice. If building 
on the existing kernel, sue the extra version defined for the 
distribution. I highly discourage doing this unless you are only 
compiling new modules into an existing kernel.
# make menuconfig
<selectr your options>
# make dep; make bzImage; make modules; make modules_install
# cp arch/<your arch>/boot/bzImage /boot/vmlinuz-<version>
Modify your boot loader include the new kernel. For EXT3 kernels, you 
need an extra step described below. RH8/9 {/boot/grub/grub.conf}

2. Kernel.org Sources
Same as above, but the first two steps are replaced with getting the 
kernel.org sources into that directory (pretty simple)

Making EXT3 support:

cd /boot/
mkdir tmp
cp init-<olderversion>.img init-<version>.gz
gunzip init-<version>.gz
mount -o loop init-<version> tmp
cd tmp/lib/
cp -f /lib/modules/<version>/kernel/fs/ext3/ext3.o .
cp -f /lib/modules/<version>/kernel/fs/jbd/jbd.o .
cd /boot
umount tmp
gzip init-<version>
mv init-<version>.gz init-<version>.img (you can leave this as .gz as 
long as you change /boot/grub/grub.conf to look for the .gz instead of 
the .img)
