I think this is what you're looking for (run at a command line):

$ optirun --status

If the discrete card is disabled, it will show X inactive. Discrete video card is off.. If it's enabled, it will show something like X is PID 24432, 1 applications using bumblebeed..

Or, if you're using KDE, you can add the widget "Bumblebee Indicatior" (sic) [1]. It shows an icon that's either black or yellow depending on the video card status.
