Managed to get ML 10.8.2 kinda' working on a Lenovo Thinkpad T410 2537-CD5 with Chameleon. But I had to delete all Intel/NVIDIA/ATI gpu drivers to get into the OSX GUI = no QE/CI and only 1280x800 resolution.
I'm kinda puzzled by this laptop. I've googled and googled but haven't found anything useful. Perhaps someone here can help me.
Many i7 T410 2537's seem to have dual GPUs, although I haven't found any info particularly on the 2537-CD5 model.
Question: Does this model have dual GPUs or not?
Lenovo Thinkpad T410 2537-CD5
Intel Core i7 2.66 GHz 620M
4 GB RAM
WXGA+ 1440x900 LCD monitor
I've tried EFIStudio with LSPCI, IORegistryExplorer, both System Info and Apple's System Information.app, lshw in Ubuntu, Device Manager in Windows XP and probably more.
All they find is Core Processor Integrated Graphics Controller [8086:0046] which means integrated Intel HD Graphics.
I'm not using any DSDT in /Extra to give more pure results.
Just seems a bit weird that a T410 with max options (from Lenovo) for CPU, RAM, monitor and HDD wouldn't have the better graphics as well. Equivalent of Apple selling the maxed out MacBook Pro with only Intel HD Graphics.
However, when looking into the raw/unedited DSDT extracted by DSDT Editor in ML 10.8.2 (only npci=0x2000 boot flag in Chameleon) I find a lot of lines mentioning Nvidia Optimus.
