The emulated video card and the output type are orthogonal. You can just
as easily be using VNC with -vga std as you can use SDL with the default
cirrus. Any of combination of output type (sdl, vnc, or none) and
emulated video card (cirrus (default), vmware and "std-vga") is
possible. Indeed, libvirt allows any of these combinations.

I see no reason to drop bochs. It's a project in its own right.
