Back into FC2's grub.conf, and adding yet another chainloader entry as below. title FC1 chainloading to (hd2) root (hd2) chainloader +1 Shutdown, reboot, then choose "FC1 chainloading to (hd2)" from Grubs menu, and Eureka, I'm chainloaded to FC1's Grub menu. Job done I think, but this has taken nearly 2 years to sort this problem. Next thing is to find out what has happened to the cdwriter that was using hdc, but thats for another day.
