I'd recommend against using the Intel framebuffer driver (in fact we've talked 
a bit about removing it--it can be harmful in many configurations).  So you 
can disable "Support for frame buffer devices" if you want.

You will, however, need /dev/agpgard, DRI, and i915 DRM support if you want 
accelerated 3d and other features.  It looks like you have those options 
correctly enabled already (though you could disable 830M, 845G, etc. support 
if you wanted).
