I grepped around and couldn't convince myself whether it can work on powerpc or not. ie. currently it's possible to enable CONFIG_VGA_CONSOLE and powerpc does have a struct screen_info defined which seems like it would allow vgacon_startup() to complete. My only concern is that someone could be using it with Qemu? cheers
