OK, two things: I did not change any BIOS mapping or drive or boot

How is it failing? It may be that your update kernel is just in
a location your bios can't load. This used to be common in old bios
versions that couldn't go past 1024 cylinders and is probably possible
again with more exotic drive configurations.
I did remove drives in order to get F7 to install at all and yes, I
added those drives on later, BUT even after doing that GRUB booted fine.
It is just that after updating the system the whole shebang comes apart
for no good reason. GRUB just ought to continue booting from the same
drive and same partition it booted from before...and it just doesn't do
that.
Also, I do not have plain simple IDE drives, but a RAID array on the
nVidia SATA controller that I want to use to boot from. In that case,
when I specify a hdx device it will write the boot loader to only one of
the drives of the mirror array, which doesn't do any good.
If bios sees the drives as separate things, then that's how you have to
install grub, since it has to call bios to load the kernel. On a real
hardware raid, bios will only see the array.
