--- Comment #1 from Niclas Zeising <zeising at FreeBSD.org> ---
Can you check that it actually is getting to use any driver when you try to
force a driver, and doesn't just fall back to software rendering?

>From a kernel perspective, there is just the i915kms.ko driver, which provides
support for all Intel GPUs.  mesa has both i915_dri.so and i965_dri.so.

Are there any error messages from libdrm, or any hints at all on what has
changed?
libdrm does not in itself pick a driver iirc, it is mesa which decides on i915
or i965 (or any other).
