    Hey,

    I am running against the SSDT wall to get AppleIntelCPUPowerManagement.kext (patched, from Multibeast for 10.7.4) working on my thinkpad 220 i7 2640m. Everything was fine in 10.7.3 but I'd like to give 10.7.4 or Moutain Lion a try (I understand ML works similar to 10.7.4 when it comes to CPU Power Management).

    I built my 10.7.3 install according to this guide: http://forum.thinkpads.com/viewtopic.php?f=32&t=102098 but unfortunately the author has the i5 version so the SSDT he uses does not work (and looks very different).

    My problem is that I extracted my SSDT tables (I get 5 files) and the structure differs a lot from what I've seen before! So I am not sure what to do:

    for example, my Name (SPSS, Package (0x0C) section contains entries like (last value increments in 1 step for every entry, 0x00000083 value increments in 0x00000100 steps)

    Code (Text):

                Package (0x06)
                {
                    0x00000AF1,
                    0x000088B8,
                    0x0000006E,
                    0x0000000A,
                    0x00000083,
                    0x00000000
                },
     
    where other SSDTs I've seen contain
    Code (Text):

                Package (0x06)
                {
                    0x08FD,
                    0x88B8,
                    0x0A,
                    0x0A,
                    0x1D00,
                    0x1D00
                },
     
    The original SSDT contains P-States in 200Mhz steps only (I guess I need 1 entry for every 100Mhz for it to work?).

    There is a Mac with the same CPU (http://www.everymac.com/systems/app...8-13-late-2011-unibody-thunderbolt-specs.html). Could that help somehow?

    Thanks for any help!

    Did you ever get this sorted out? I have an x220 that I'm wanting to run ML on. I'm in initial investigation mode right now :). I have bought a compatible wifi card and patched the bios with the non-whitelist version.
