    works as 1.1 for some reason, but i believe it's just cosmetic bug.

    cuz what reported by sys profiler is jsut one key from ioreg, and the key can be easily changed .

    better to use lspci for osx.

    Yes, I recall that an OS X openCL benchmark on a flashed radeon 4870 gave results that were incompatible with PCIe 1.1 (i.e. bandwidth exceeded 2.5. GT/s) .
    The same may be true for flashed radeon HD 5xxx cards.

    Boot to Windows and use GPU-Z instead.
