Well, *if* there should be heavy resistance against this patch, we may
postpone it. But I consider the feature useful to identify the cursor
position and check visually the liveliness of QEMU.

However, the VGA blinking is a feature that should go in, specifically
as there is no impact on wakeups and it fixes an emulation deficit.
