I've put /boot on md raid1 on a lot of machines (always drives small
enough to be MBR based) and never had any problem with the partition
looking enough like a native one for grub to boot it. The worst thing
I've seen about it is that some machines change their idea of bios
disk 0 and 1 when the first one fails, so your grub setup might be
wrong even after you do it on the 2nd disk - and that would be the
same with/without raid. As long as you are prepared to boot from a
rescue disk you can fix it easily anyway.
