Bug Description
1) The Linux module mbp_nvidia_bl needs to be autoloaded to provide the backlight device for the NVidia card in 3.1 and 4.1. The fix for this is detailed here, and this should be carried by us as it currently does not work. http://
Workaround: load the module by other means, either on-demand with modprobe or by adding the line to /etc/modules
2) G-P-M gets confused by the phoney MacBook Laptop Panel HAL device (that is actually dead since the addon providing its services doesn't work for NVidia). Upstream HAL received this fix to only spawn this for the relevant models. http://
Workaround: comment out the <spawn> element for the laptop panel in the file.
