Some descriptions of the MBR code for lilo and grub.

To detect grub, I would mask off the variable information, like the
partition table, Bios parameter block and NT drive serial number. 
I would then compare the installed MBR with the /boot/grub/stage1
(should be somewhere) installed on the machine.
