Not disputing this, but how did you come to that conclusion? 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
