You're welcome.
"/etc" was a typo. It was meant to be "/boot/...". Sorry.
Having "groot=(md0)" was definite;y wrong because grub1 doesn't
understand mdraid.
I don't know why it worked before. Maybe your hosting company created
the grub entries manually rather than via update-grub.
(If this is a VM, you won't be able to use either xen or kvm.)
