I want to thank Jordan, with whom I had the pleasure of chatting via the 
#grub IRC channel at Freenode Sunday evening, immensely for his help in 
solving this problem!  Though I think the loss of the initrd file had 
something to do with the filling up of the /boot partition during a 
software installtion from within Synaptic, which is the reason I decided 
to enlarge that partition, by following the procedure outlined above, I 
was in fact able to restore my machine to a bootable state.

This whole experience taught me both a lot more about GRUB than I really 
wanted to know just at this point and that the subject is a lot more 
complex (or at least it seems so) than I had ever imagined.  Though 
surely comprehensive, I think the way the GRUB manual is organized makes 
it hard to use as a learning resource - it reads more like a reference 
manual than a tutorial - which may be alright, if there are some good 
up-to-date HOWTOs out there someplace.

I just know that without Jordan's help, I likely never would have been 
able to find an fix this problem, since I hadn't known anything about 
initrds and UUIDs, and only enough about utilitiesss like fdisk, for 
that matter, to be able to get by before going through what I did.

Thanks again ever so much to Jordan, both for his suggestions and for 
the time he gave so generously last night.  I am deeply in his debt!
