I used the following a while back and it worked for me....

Setting up GRUB: (assuming you've already installed it)
------------------------------------------------------------------
# grub
grub> root (hd0,0)
 Filesystem type is ext2fs, partition type 0xfd

grub> setup (hd0)
 Checking if "/boot/grub/stage1" exists... yes
 Checking if "/boot/grub/stage2" exists... yes
 Checking if "/boot/grub/e2fs_stage1_5" exists... yes
 Running "embed /boot/grub/e2fs_stage1_5 (hd0)"...  16 sectors are
embedded.
succeeded
 Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p
(hd0,0)/boot/grub/stage2 /boot/grub/grub.conf"... succeeded
Done.

grub> root (hd1,0)
 Filesystem type is ext2fs, partition type 0xfd

grub> setup (hd1)
 Checking if "/boot/grub/stage1" exists... yes
 Checking if "/boot/grub/stage2" exists... yes
 Checking if "/boot/grub/e2fs_stage1_5" exists... yes
 Running "embed /boot/grub/e2fs_stage1_5 (hd1)"...  16 sectors are
embedded.
succeeded
 Running "install /boot/grub/stage1 (hd1) (hd1)1+16 p
(hd1,0)/boot/grub/stage2 /boot/grub/grub.conf"... succeeded
Done.

grub> quit
------------------------------------------------------------------
Here is how /boot/grub/grub.conf is: (/dev/md0 mounted as /boot)
(Assuming kernel is installed as /boot/bzImage, and RAID1 support
compiled into the kernel).
------------------------------------------------------------------
# Boot automatically after 30 secs.
timeout 30

# By default, boot the first entry.
default 0

# Fallback to the second entry.
fallback 1

# For booting with disc 0 kernel
title  GNU/Linux (hd0,0)
kernel (hd0,0)/bzImage root=/dev/md1

# For booting with disc 1 kernel, if (hd0,0)/bzImage is unreadable
title  GNU/Linux (hd1,0)
kernel (hd1,0)/bzImage root=/dev/md1
------------------------------------------------------------------
