Some drivers support being a module, others (e.g. atyfb) don't (yet).

If you have no screen drivers, you'll see nothing until you insmod a frame
buffer device.

Still complaints about

fbcon_setup: No support for fontwidth 8
fbcon_setup: type 0 (aux 0, depth 8) not supported

?? Did you do `make depend' after changing the config?
