LVM I would agree.  A separate /boot where grub can locate its files are
required.

Again, with LVM it makes sense.

Correct.

That is when IIUC you install grub loader to something besides the MBR. 
If GRUB stage 1 is installed in the MBR, it works fine (though finds its
files on one of the disks).  It even, since it is a RAID 1, works with a
fallback to the second disk in case the first disk failed.

BTW, did you set, in Yast, System, etc/sysconfig Editor, System,
Bootloader, LOADER_LOCATION to mbr?

I'm glad my system does not have artificial intelligence and know what
you said.  It might decide it cannot work as it is now and cause me
problems.  I boot from a system with software raid 1 / with /boot on it
every day, with 10.2 (though it has worked since at least 9.3).  I will
say I have had problems with Yast with 10.1 and got used to installing
grub manually every time there was a kernel update.  10.2 just works
correctly (i.e grub should not be messed with at all with a kernel
update).  So it does boot with /boot on a software raid 1, WITH the
caveat grub stage 1 needs to be installed in the mbr.
