Would the presence of i915drmkms cause i915drm to fail to _compile_?

An issue trying to make the product work on a particular monitor.  I'm
relatively peripheral to that project; they appear to be Easter egging,
trying various things in the hope that one of them will work.  The
reason i915 support is a suspect is the boot-time message from
i915_firmware_load_error_print about CONFIG_EXTRA_FIRMWARE or "your
initrd/initramfs image" (which really sounds to me like a Linuxism that
never got fixed when it was imported to NetBSD - the code is also full
of -ENOENT and -ENOMEM and the like, also a Linux signature).

Unfortunately the issue manifests for only one customer, on the far
side of the planet, so the change-test-debug cycle time is on the order
of days.  And the monitor that provokes the issue is expen$ive enough
that getting another one for testing is prohibitive.
