Rebuilding the kernel is a quite simple operation.
First, prepare the build directory:

cd /usr/src
tar -xjf /mnt/cdrom/usr/src/kernel/linux-2.6.18.tar.bz2
ln -sf linux-2.6.18 linux
cd linux
zcat /mnt/cdrom/usr/src/kernel/linux-2.6.18-*.diff.gz | patch -p1
zcat /proc/config.gz > .config

Now configure and build the kernel:

make menuconfig
make

Then install it:

cp arch/****/boot/bzImage /boot/linux-2.6.18-test

The "****" stands for your architecture name.

Configure bootloader (I did it once and always have "stable" and
"experimental" kernels):

image=/boot/linux-2.6.18
	label=good
	root=/dev/sda1
	read-only

image=/boot/linux-2.6.18-test
	label=test
	root=/dev/sda1
	read-only
	append="panic=5"

Note the "append" parameter - if kernel will be unable to run init,
it will reboot in 5 seconds.

Reinstall the bootloader:

lilo

Ask the bootloader to load experimental kernel on next boot:

lilo -R test

Reboot with your new kernel:

reboot
