Hi Michael,

understanding of a frame buffer is an area of (usually video) memory
representing the image shown on a screen.  You can have more or less as
many of those as will fit into video memory and flip between them.  You can
also have up to 32 virtual screens (the hardware supports 64).

Ok, I might describe it vague, so yes - I need more virtual screens each of
them with support of framebuffer. So if I enable, for ex. 4 screens (or
monitors?), then I expect to have also /dev/fb0 - /dev/fb3 devices, writing
to which will be displayed on appropriate virtual screen.
