  Yes, identical. I'm pretty sure that I had the same LBA/LARGE/NORMAL.
One source of frustration is that the "auto" option would pick different

  I would have the libsa read a file, i.e. /etc/bootdefault (a la BSDi)
or maybe even /etc/lilo.conf to get that junk. Yes, agreed... getting it
to start up the kernel properly will be a challenge, but lilo is open
source as well, so I read its code. 
  I would start by getting lilo to load our /boot that has ext2fs support
in it.
