The nouveau code used to call drm_fb_helper_initial_config() from nouveau_fbcon_init() before calling drm_dev_register(). This would probe all connectors so that drm_connector->status could be used during backlight registration which runs from nouveau_connector_late_register(). After commit 4a16dd9d18a0 ("drm/nouveau/kms: switch to drm fbdev helpers") the fbdev emulation code, which

Several nvidia-based systems don't support backlight control via the standard ACPI control mechanisms. Instead, it's necessary for the driver to modify the backlight control registers directly. This patch adds support for determining whether the registers appear to be in use, and if so registers a kernel backlight device to control them. The backlight can then be controlled via

Straight port of Matthias Hopf's KMS backlight code for xf86-video-intel, with reformatting and a couple of minor cleanups. Works fine on my MacBookAir2,1.
