--- Comment #6 from Brad Campbell brad@fnarfbargle.com 2011-09-28 00:39:56 PDT --- Ok, so some kernel version backtracking shows that this worked in 2.6.39. I've run a bisect between 2.6.39 and 3.0-rc1, but I keep getting lost in the major displayport re-write that happened in there.
When the machine is booted using Bootcamp v4 directly (not via refit) the bios sets up the thunderbolt bridge, makes all the PCIe end devices visible on the system and wires the displayport through to the radeon.
I've added the regression tag to this bug.
I'm quite happy to spend time on irc running crash and burn cycles as required.
