I don't know if this would be of any help to you, but I have a vdev live
iso that I made using Ralph's vdev packages back in October. After reading
this thread, I decided to install it and upgrade to the 4.9rt kernel. It
boots normally.

What I can't seem to do is make a bootable iso with the 4.9rt, even after
upgrading live-boot, et. al. to the ascii versions. (There's a problem
with the bpo versions of live-boot missing some parts in the initrd
related to overlayfs and nls_ascii).

If you want to try the October live iso, let me know.
