Yep. Check which ioctls fail then try to reproduce outside of Mesa or hardcode the result. Overriding PCI ID via INTEL_DEVID_OVERRIDE is unlikely to help e.g., https://lists.freebsd.org/pipermail/freebsd-x11/2019-January/022551.html If you still have no clue try playing with sysctls under compat.linuxkpi via /boot/loader.conf.
