[Nouveau] Framebuffer double buffering (via FBIOPAN_DISPLAY)

[Michael T. Kloos]

Does NOUVEAU support mmaping a double-sized Framebuffer?
When attempting to run, where fd refers to "/dev/fb0":

mmap(ptr, screensize * 2, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);

I get back an invalid argument error.  This doesn't happen if I only
request a single screensize.  Is this a limitation of the driver?
