Yep, that's nice ;) In addition you might want to see if the boot loader is 
installed in /dev/hda | /dev/sda | /dev/whatever or in /dev/hda1 for example 
if this is a multiboot system (bsd, linux, window$). Long time ago ;))) I 
used the Win9x MBR with active partition /dev/hda1 where my /boot was (saved 
me a lot of pain when I had to reinstall win9x).

There are some more boot loaders I know of:
	aspldr - asploader - it uses some sort of dos booting -> mbr.sys, 
bootsect.sys, aspldr.sys, aspldrcd.sys and mouse.com. It's mbr.sys contains 
only 3 > 4 byte strings: "ro;^\uj", "VPP2" and "MBR Error". I have one 
ASPLinux arround so if ye are interested I can look further...
	sbm - Smart Boot Manager, which I saw in debian distro as far as I remember. 
It's a nice thing ;) can boot from CD on systems without CD-Rom boot support, 
can be installed on floppy and it can install itself on hdd later... used to 
love it year or two ago...
... and... maybe, this can be solved for fedora by simply putting an 
/etc/bootloader.conf with a single line bootloader="whatever" ;)... just an 
idea ;)
