When doing a kexec (WIP) on ARAnyM while the screen was blanked, the

falcon_blank() clears several videl registers, while falcon_detect()
reads them to detect the current video mode.
I suppose we can't just leave the cleared registers loaded when kexec
support is compiled in, and effect screen blanking in another way
(color map)?
Can the screen be blanked/unblanked from user space (fbset)?
You can unblank from userspace.
Probably the right way is to convert atafb to use a platform device first,
and hook up its shutdown() method later.
