1: make xconfig

2: make dep bzImage modules modules_install

3: cp your created bzImage to the /boot/ directory

4: add your new kernel to your boot loader

What distribution do you use? There might be a specific method for yours.

The generic is:

*as user:

cd linux-2.6.18
make oldconfig => this will take your running /boot/config-`uname -r` file as a reference.
change your settings here (don't modify by hand the .config!!)
make clean
make

*as root:
make install

Then update your /boot/grub/menu.lst to add a new section for your new kernel.

Keep your old kernel and old kernel section in grub in case something goes wrong!

ps:
google is your friend also
