Debian on a Pi means you don't/cant' have the whole /opt/vc userland stuff, some of which came from Broadcom. Without that the Pi is just a slow computer. The magic is probably Pi-specific but /opt/vc/src/hello_pi has working examples of things like OpenGL ES and the assembly code to do an FFT on the GPU. I tried straight Debian, on 2 of 3 machines I'm sticking with Raspbian. The folks at https://www.raspberrypi.org/forums/ are pretty good too, some of the original Pi engineers are in there.
