That is actually just the same, since wsdisplay attaches at radeonfb.
The framebuffer driver just replaces the more generic vga @ pci. For such
drivers I would consider going the third aproach, i.e. integrate the
chip specific DRI part in the framebuffer driver, maybe controlled by
a compile time option (RADEONFB_NODRI or something). Theoretically we
could split those two subsystems, but I'm not sure it is worth the effort.
