I found this out the hard way. I'm still a bit confused that Grub
would modify an exiting device.map file when that could cause issues
(case in point).

No, no it didn't. However, that's where 'linux rescue' comes in
handy.

Yes, hd(0,0) was now the new IDE drive with sda becoming hd(1,0)

I tried this, but did not have any luck(?). Was still hanging up at
"GRUB" (no more beeps tho!).
Alternatives...
Since this did not work:
# grub-install --recheck /dev/sda
Probing devices to guess BIOS drives. This may take a long time.
/dev/md6 does not have any corresponding BIOS drive.
I had to run:
# grub --device-map=/boot/grub/device.map (*)
grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0xfd
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 22 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+22 p (hd0,0)/boot/grub/stage2
/boot/grub/grub.conf"... succeeded
Done.

(*) device map has been edited to put IDE drive at the end
Rebooted and all was well once again. Phew!

Wasn't a bad guess at all, and probably would work in other
configurations and/or situations.
Thanks for the assistance!
As a side note, what other OS could possibly cause you to start
pulling hairs, yet be so happy when you finally fix the problem with
the assistance of others? What a trip! :)
