I gave up and took out the grimy linoleum in the fridge nook, leaving the plywood under it. The plywood needs to be replaced, really, because a two-inch strip to the right has rotted; I'm guessing the refrigerator in there leaked, or didn't have a drip pan, or the drip pan was never emptied. (On seeing this, I promptly emptied the drip pan on this one, which had three-quarters of an inch of water in it.)
Anyway, I'm still working on the floors and cabinets, but... the kitchen is basically done. I was going to clean it, then make breakfast, but it's already afternoon and I'm just too hungry, so I guess I'll cook breakfast tomorrow. I have some fresh eggs from my dad's chickens; an omelette sounds pretty good.
