Mmm, looking at that again, most of my idleness patch is actually
already upstream.  What wasn't pushed is what is specific to xenfb:
transmitting the idleness to the backend.  For this xenfb needs to get
idleness information.  Below is the patch that does that, you can just
fold it in your qemu-upstream/0008-xen-add-framebuffer-backend-driver.patch
About GUI_REFRESH_INTERVAL, you can just move it to a header.
