What's a good cereal mash time/heat for buckwheat?
I'd get it as close to boiling as you are comfortable, and then rest it for 10 minutes at least.
Awesome. I don't yet have a corona mill but I do have a food processor. Will that suffice?
Probably not but try.
Buckwheat is fairly large. I would do a test run first.

You will most likely ruin your food processor if you try to crush any appreciable amount of it. You'd be better off with a cheap coffee/spice grinder. Or a mortar and pestle!
