THey have a standard VGA interface for text mode, but they all tend to have a "stop behaving like a VGA card and go native" switch for running in non-banked modes. This is different for every card.. which is why syscons can't do it as-is. Syscons would also have to stop things like any in-flight busmastering DMA etc.. The only way to do this is to move the hardware-specific parts of XFree into the kernel and provide a ddx device for XFree to use.
