One I like to name of the file system to be something else. This way apps can move over to it. You will still be able to do the above. I plan to have for each framebuffer
/dev/gfx/frameX.
So say your card can do double buffer you could do
cat /dev/gfx/frame0 > file1 cat /dev/gfx/frame1 > file2
So you could access the double buffer as well :-)
