I'll just note that I ran into some of these problems again in conjunction with some more upgrades. I'm getting much too familiar with the internal GRUB commands to find partitions and to find and display files.
I feel like the proper solution would be a graphic repair interface for GRUB. In almost all cases I was able to boot the machine somewhere--but they could still put the utility on the live CD.
