Yeah I misunderstood the question, I think. The *.mod files and grub.cfg can be 
essentially anywhere with the current version of GRUB2. I can't vouch for 1.98. 
But 2.00 will find these files on extended partitions, buried inside LVM LV's, 
and even on a six disk RAID 0. It's kinda amazing actually.
