I would agree except you need to go to gnu.org and get the grub manual. It will tell you what it can't or can map. I believe that if you can boot a device then grub can boot it as long as it can be mapped through its device.map. anyway if grub manual says it can't be done then it acceptable. Redhat doesn't necessarily speak for grub, only what they support.
