Yeah, I really like those. I've come across three named dragons being resurrected by Alduin so far. I think the places match up with that dragon-burials map the Blades woman has sitting on her table.
One of them always glitches for me though. Its the one on the road up from Windhelm past the mill. Alduin always misses the dragon-burial mound with his shout, and the dragon glitches and just climbs out of the ground fully formed. The others work fine though with a bone-dragon emerging first.
