Probably not as it is, unless your firmware sets up some graphics  
mode. If it does you still need to pass some geometry information to  
the driver as device properties ( macppc and sparc64 already do that,  
you need width, height in pixels, depth in bits, is_console must be 1  
if the driver is needs to call wsdisplay_cnattach() - that way the  
driver can stay free of any firmware dependencies )
Eventually it will implement mode setting, then it will only need  
is_console.

have fun
