generate a kernel dump, which can then be grokked by crash to generate a

In either case, you have a fair bit of RTFMing to do.

And then after wasting all the time, you'll discover that you're not
getting a useful crash in the first place.

Hmmm, you paint a rosy picture ;-)

It's definitely:

1) A learning curve

2) Doable.

But if I do nothing, my choices are:
1) hope to get lucky on some future kernel update

There is precedent for that. Circa Fedora 9, or so, there were something like three or four kernel updates in a row before the kernel managed to boot succesfully on one of my machine.
