Since we were on BSD LILO or Grub were not an issue (we were dealing w/ 
the BSD boot loader), but in answer to your question yes LILO is capable 
of serial boot.  Information here:
http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-boot-loader.html
information is included for LILO, GRUB, and SYSLINUX.  For anyone 
considering running a linux serial setup, pretty much everything seems 
to be covered here:

Enjoy!
