Setting 'nomodeset' on the kernel command line disables all graphics drivers with modesetting capabilities; leaving only firmware drivers, such as simpledrm or efifb.
Most DRM drivers automatically support 'nomodeset' via DRM's module helper macros. In xe, which uses regular module_init(), manually call drm_firmware_drivers_only() to test for 'nomodeset'. Do not register the driver if set.
