Any of those should work.

You can individually install each disk independently with:
 # grub-install /dev/sda
 # grub-install /dev/sdb

Or, more conveniently, you can install to the md device, and let the
new code in grub-install sort it out (recommended):
 # grub-install /dev/md0

So let me stress again that these updates should only be applied to a
dev/test system and tested there.

And yes, it would probably not be a good idea to apply these to a
system that was manually patched. That would invalidate the testing
that I'm looking for...applying these updates to a stock, up-to-date
Hardy test system.

Thanks for volunteering, Bill!
