Lilo on a > 2TB device is risky.  It has worked exactly once for me, and
never again.  Also, a > 2TB device requires a GPT disk label in order to
not eat the file systems created upon it.  Lilo cannot install to a GPT
disk partition last time I tried.  It barfed badly.

Work is about to begin (as Peter said) to make grub handle GPT disk
labels, which is necessary for > 2TB block devices.  This will allow
