beagleboard xm and overlays

I have a beagleboard xM with kernel 2.6.39 and I have /dev/fb0 and /dev/fb1
/dev/fb0 is the main framebuffer and I already use /dev/fb1 for
something(an overlay).
Can I get another /dev/fb2 for another overlay? If so, how do I configure it?

you increase the number of frame buffers in the kernel config from 2 to 3
