I recall Linux/PPC kernel developer Benjamin Herrenschmidt saying ages ago that it would technically be trivial to write a tool that accesses the Open Firmware device tree to adjust the iMac's built-in monitor's features (brightness, contrast, geometry, etc.). I'm wondering if anybody ever coded such a tool? Otherwise, would anyone be willing to study the Darwin source code and port it to Linux?
