Ahh, I think I found that which you seek.

http://www.tldp.org/HOWTO/mini/Boot+Root+Raid+LILO-3.html

(Don't forget the mini-howto's...)

Basically, it looks like you need to make a pair of lilo.conf files.
The boot= line should point to either of /dev/hda or /dev/hdc,

mini-howto.  It's a little out of date, but I think still relevant.
