Which FreeBSD version are you exactly using?  The only difference is
that instead of using special FreeBSD native calls for PCI info we use
LinuxKPI as in the original (to avoid conflicts).

The one thing I could think of is that something is not set correctly
in LinuxKPI but when I checked I hadn't noticed anything.

But if this fails I would have expected it to fail queally for Intel
and AMD.

What is consuming the DRM_IOCTL_GET_PCIINFO ioctl anyway?  I checked
xorg-server and mesa-dri and mesa-libs and couldn't find any use.
