    I didn't see this result for my 2008 Mac Pro (8 GB RAM, ATI Radeon HD 2600):

    All,
    For the record, I came to the conclusion that the "efifb.c patching" is the
    wrong approach.
    Normally the bootloader is responsible for querying the graphics hardware
    properties (FrameBufferBase, PixelsPerScanLine, HorizontalResolution,
    VerticalResolution), and then it passes them to the kernel through the
    "linux_kernel_params" structure.
    Grub2 can do that, for both UGA (PCI scanning trick) or GOP (returned by the
    official EFI API).
    The kernel should not have this list of hard-coded values. Furthermore, these
    values are not unique for a Mac model, but can very depending on the amount of
    RAM and possibly also on the connected devices at boot time.
    See user submissions in this thread.
    On top of that, these values in efifb.c are really misleading : someone looking
    for a reason why the EFI boot does not work on a brand new model might think
    that his model is missing in the list and that causes the problem, which is a
    wrong track.
    I think we should remove these hard-coded values from the kernel and only rely
    on values passed by the booloader (which should be dynamically queried), so
    that it will work on all models.

    This is the output from my 17" MacBook Pro (early 2008), 4GB RAM, 512MB NVidia 8600M GT.

    Code:
     <"Apple Inc.">
     <"MacBookPro4,1">
    FrameBuff erBase: 0xc0060000
    PixelsPerScanLine: 2048
    HorizontalResolution: 1680
    VerticalResolution: 1050
