More precisely, the framebuffer driver contains all the chipset and
therefore the memory (amount/type) detection stuff. It checks for
eventual Turbo/Commandqueue capabilities (which differ significantly
depending on the actual chipset used) and sets up a memory heap taking
all the hardware specifics into account. Moving the memory management to
the DRM module will result in a lot of duplicate code and a lack of
common memory management.

If you don't want to use the framebuffer, start it with no video mode
specified or with mode=none (or mode:none if as kernel parameter)
