Ok.  I'll give that a try tomorrow.  Just a couple of questions.

install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0,1) /grub/stage2 p
(hd0,1)/grub/grub.conf

It looks like this mixes paths relative to root and relative to /boot.
Did your test system have a separate /boot partition?  The --stage2
argument is "os stage2 file" according to my man page. Should this be
relative to root even with a separate /boot partition?

Also, why are the exact same root and install commands run twice in the
log you show?  Is that just a duplicate, or does it need to be run twice
for some reason?

grub> root (hd0,1)
grub> install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0,1)
/grub/stage2 p (hd0,1)/grub/grub.conf
grub> root (hd0,1)
grub> install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0,1)
/grub/stage2 p (hd0,1)/grub/grub.conf
