The open-source R500 support from the
Radeon driver, now includes TV-Out capabilities. Through a series of three commits this morning to the xf86-video-ati git tree, TV-Out support is now detected through the AtomBIOS. Reading the TV standard is also done through this Video BIOS abstraction layer. If you're interested in having open-source TV-Out support on your R500 graphics card, be sure to check out the latest git code. The RadeonHD driver has yet to support this functionality. David Airlie has
blogged about these three commits he authored and additional information is in the
Radeon IRC channel.
