I had the screen go out on my droid, I just flashed back to 2.0.1 using rsdlite (easy to do this blind) and left it. Even if they fixed the screen they would have no proof of rooting, just that I somehow did a screen-free factory reset and never took the 2.1 ota update.
My third replacement with a bad camera, however, I flashed with rsd and then force-updated to 2.1 using the old official ota update.zip file. Worked great.
Droid number 4 seems to be going strong (knock on wood)!
