You forgot to add the initrd stuff to the new kernel image "stanza":

   initrd=/initrd.img   <---- add this line

You don't have to modify the "image=/vmlinuz.old" stanza.

Just boot up in the old kernel, edit your /etc/lilo.conf and re-run 
"lilo" and it should be fine.

The warning is due to the fact that you probably have your BIOS set to 
use one set of "geometries" and Linux is using another.  I use the "LBA" 
setting here in the BIOS setting for my HD and it seems to work OK.  The 
other setting "Normal" seems to give me this message.  It has never 
caused any problems... just a "warning"...
