By the teen years I pretty much expect the kids to be responsible for their own time management. (both going to bed and getting up). They don't always make smart choices, but they live with the fall out. As long as he was getting up for school on time, I'd probably stay out of it.

! Our oldest is 11.5 and lights out is between 8 and 8:30. He wakes up around 6:00. My younger kids are in bed between 7 and 7:30 and also get up around 6:00. They are all very happy and rarely sick so I'm hoping the sleep they get has something to do with that!
IMHO it is important that kids still have guidelines (if not rules) and be expected to follow them.
I think the biggest mistake I made was allowing him to have a tv in his room. Like alot of other posters here he also had the basement to himself, with a bedroom, mini-kitchen and playroom, never again!
At the least, it's a compromise and that's what he's really looking for at the moment

I read a study recently that when kids hit their teen years, their sleeping schedule shifts. They naturally won't get tired til later, and will sleep later. The study was talking about how moving the high school start time back an hour decreases tardies and truency. So his changing sleep schedule is biological. Something to think about!
If he has aspirations beyond high school and wants to pursue a career, then he needs to get to bed earlier. If he just wants to 'get a job' after high-school, then he can just maintain the current track. It is up to him, but gosh, you have a lot of input at this point.
Please, continue with encouragement of an earlier bedtime. Nothing, and I mean nothing good, comes from staying up most of the night.

I would probably let this be between my stepson and his father. I'd stay out of it.
