Yes it's correct. Kernel provies framebuffer for graphical display. However X
comes with it's own set of drivers and uses them. If any of pre-built drivers in
X does not work, you can opt to use framebuffer driver.
So both kernel and X provides their own graphics driver. It's been a long debate
about whose duty it is and who has done it better.
As a user we have more than one choices. (But it's not always better. If you
ever run into troubles with X and you are using frame buffer, you need to manage
two beasts, kernel and X. According to some reviews I read, it's a *real* scary
