It needs wscons, support for mapping PCI BARs via /dev/ttyE0 and might 
need a way to access PCI IO - on macppc it just maps a certain range 
via /dev/ttyE0 which the underlying wsdisplay drivers redirect to 
wherever the corresponding host bridge keeps PCI IO addresses. At least 
if you use ppc_video.c in X. Some drivers ( like those for mach64 and 
radeon devices ) don't need IO access, no idea about S3 though.

have fun
