Surely there are other devices out there that are sensitive to unexpected reads?
Oh yeah, I just checked out the way things _really_ work... hmmm, maybe we need a vm flag called "VM_DEVICE" which can exist at the same time as the VM_LOCKED flag and inform the mmap() code you mention not to try to force the pages in because "they already are in".
I bet this nuance slows down the X server startup a bit.
