I tried it out in arm64 debvm, and both the kernel and Xorg drivers are detected just fine according to the log. I only get a black screen, which could be the result of a missing VGA BIOS or the missing unblank Port I/O in the driver (I doubt the VGA ports are hooked up on arm64 qemu), but there is a good chance that it's currently working for someone else.
