I think you can make burnt ends out of any part of the brisket. Just cook it like you were going to eat it sliced but instead of slicing it, cube it up in roughly 1" sizes.
I just did some burnt ends tonight by throwing my cubes (1/2 were from the point and 1/2 were from left over flat) in some au jus from the drippings, lightly season them with some more rub that initially used when cooking, smoke for about 30 minutes or so at 275* to dry them a little bit. Then I start coating them with my BBQ sauce every 30 minutes for another 90 minutes or so.
Then viola:
They were tasty. My neighbor and i ate them while drinking beer and watching the ESPY's
