Huh? The bootloader does not need to know anything about raid.  It
just uses int13 calls to read sectors off a "disk".  The fact that the
disk is a software raid5 array is completely hidden from grub.  This
is functionality that has been available via dmraid for some time and
is now being made available with the MD infrastructure and mdadm.
