Mm. The console VT switching is an ugly hack to deal with the fact that
in the x86 world graphics reinitialisation is handled by userspace, and
so we otherwise have races between graphis reinitialisation and X. I
don't think it's helpful to further perpetuate that hack, especially
when you have another mechanism for requestng a screen refresh.
