In this context I would think more about X11 or vnc driver

That's why I proposed to pass variable name to the parameter. Not having 
a framebuffer address means that xnu will boot in blind mode. So one 
should be able to specify video drivers for grub and xnu separately:
E.g
gfxmode=vnc
[..]
menuentry "Darwin" {
     xnugfx=vbe
[...]
}
