Phoronix: Radeon Driver Gets Golden Registers In Linux 3.10
A second Linux 3.10 Radeon DRM driver pull request was submitted by AMD's Alex Deucher. The pull request sent to Red Hat's David Airlie for the DRM sub-system mentions the "golden registers" addition as being the highlight of this batch of new open-source AMD Linux graphics code...

I say 'more or less work' because of the comment above about 'stranger behavior' or 'bugs' on certain cards. Its very possible that some or all of the card specific bugs the FOSS teams have hit are simply because registers are being plugged in the wrong order and hitting unknown and untested register configurations. If thats the case, then using these -correct- registers should automatically fix those bugs.
Clearer now?

That's good to know. Though I'm still curious, what exactly makes those registers "golden"?
