so if it's built in, then why does it not load?
I am thinking that they changed how you define vfio-pci options in some way.
I define them in a config file in /etc/modprobe.d/ and then rebuild all 
ramdisks.

$ cat /etc/modprobe.d/rad-vfiobind.conf
options vfio-pci ids=1002:7340,1002:ab38

on boot the card is not owned by vfio-pci or any driver.
