GRUB 0.9x can certainly boot from RAID1 - I'm doing that on several systems
currently. It only works because GRUB can access each disk individually[1]
and GRUB needs to be installed on both disks. In such cases, I make /boot a
RAID1 array without LVM on top and have the other filesystems as separate
RAID1/5/10 devices with LVM on top of them.
[1] The on-disk format of a RAID1 component disk is almost the same as
the on-disk format of a disk not part of a RAID1 set. This isn't the
case for RAID5 or 6, for example.
