Wait I wasn't done! Hit send by mistake...
You *CAN* have more than one version of the same kernel on the system, if
you need to. You'll need to edit the Makefile in the root of the kernel
source tree. Right at the beginning you'll see something like:
VERSION = 2
PATCHLEVEL = 2
SUBLEVEL = 16
EXTRAVERSION =
What you need to do is set EXTRAVERSION to something... then your kernel
will be called 2.2.16-whatever-you-called-it. Your modules directory will
have the same name. What you do now may be distro-specific, but generally
what you'll do is
# cp System.map /boot/System.map-2.2.16-whatever-you-called-it
# cp arch/i386/boot/bzImage /boot/vmlinuz-2.2.16-whatever-you-called-it
Then edit lilo.conf to add an entry for that specific kernel, and run
lilo. Then you should be all set.
