Hi John,
Since I run RH and use the initial ramdisk stuff, I do the following
after the compile:
cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-$version-$date
( I like to keep the version and date of my kernels)
cp /usr/src/linux/System.map /boot/System.map-$version-$date
cd /boot

I use symbolic links for the kernels I have built and that way I don't
have to mess around with the lilo.conf once I have it set. I also always
keep the last stable kernel that I used, just in case. (school of hard
knocks or unbootable boxes).
First I'll remove the old links and then I'll link the kernels to
something like:
rm -i System.map vmold* vmnew*
ln -s vmlinuz-$oldver-$olddate vmold
ln -s vmlinuz-$version-$date vmnew

I make the initrd images and link them:
modprobe loop        (load the loop module)
/sbin/mkinitrd initrd-$version-$date $version 
(version name as found in /lib/modules -i.e. 2.2.16 etc.)
ln -s initrd-$oldver-$olddate vmold.img
ln -s initrd-$version-$date vmnew.img

And link the System map:
ln -s System.map-$version-$date System.map

And then run lilo:
[root at telecaster boot]# /sbin/lilo
Added New*
Added Old

My boot dir will look like:
[root at telecaster boot]# ls -l
total 3640

My lilo.conf like:
boot = /dev/hda
# timeout = 500
prompt
  vga = normal
  read-only
map=/boot/map
install=/boot/boot.b
image = /boot/vmnew
  label = New
  initrd = /boot/vmnew.img
  root = /dev/hda1
image = /boot/vmold
  label = Old
  initrd = /boot/vmold.img
  root = /dev/hda1
other = /dev/hdc1
  label = WinNt
  table =/dev/hdc
  map-drive =0x80
  to =0x81
  map-drive =0x81
  to =0x80

Hope it helps!
