So we could either revert my patch and disable CONFIG_X86_SYSFB (was there a
special reason to enable it or just default policy?) or we wait until these two
patches end up in Linux tree and then revert mine in favour of those. I am not
sure whether they end up on a stable tree if simplefb is as "in development" as
it sounds to me.
