I've been having good luck with my /boot on a separate 1GB RAID1 btrfs filesystem using grub2 (2 disks only! I wouldn't try it with 3). I should note, however, that I'm NOT using compression on this volume because if I remember correctly it may not play well with grub (maybe that was just lzo though) and I'm also not using subvolumes either for the same reason.
