The boot steps shown up to now rely on the assumption
that the compressed kernel can fit in half a meg of
space. While the assumption holds most of the times, a
system stuffed of device drivers might not fit any
more. ... new machinery is needed to fix the problem.
This something is called bzImage, and has been
introduced in kernel version 1.3.73.

use patch with patch file
see man patch
requires you have the right kernel source the patch
applies against
It is used
patch -p0 < patchfile
man patch to read more about patch

just a note you can build newer kernels slightly
differently see the README in the source directory
make O=/home/user/build/kernel menuconfig
make O=/home/user/build/kernel
sudo make O=/home/user/build/kernel modules
modules_install
The file you want to copy is
/home/user/build/kernel/arch/i386/boot/bzImage
put it somewhere like /boot/vmlinuz-2.6.11.6
Note:
reconfigure/reinstall your boot loader for the new
kernel or you will not be able to use it
I use LILO but there is also GRUB.
Read man pages/online docs first and test it out.
