Nonetheless, if the user has two or more loaded drivers in his system, the force option will not work as expected because IGT will take the first driver found at /dev/dri. This problem can be reproduced in a QEMU VM that using Bochs and VKMS. This patch handles this scenario by ensuring that IGT uses the forced module specified via IGT_FORCE_DRIVER.
