Neither do I, but I have Grub2 (from Debian amd64) and OpenBSD amd64 ;) You don't need to install any Gnu/Linux system to have bootloader from Gnu/Linux. You just need to prepare pendrive to boot liveCD *once* and install lilo or Grub2 bootloader, but not need to install the whole system. I must admit that I have additional 50MB partition with ext2 filesystem for bootloader.
