Good thing I removed the logic board, I found a screw loose in the system. Could have shorted it out.
It took 15 min. to dimantle and put back together for me to do the posting. I did not look at the chipsets. I will look at the high res photos to see but I think there are heatsinks on them.

Not sure if it's the same for the PC MXM cards or not tho.
'PC' video card ROMs are only 64K, whereas 'Mac' cards are 128k. The reason for this is so that Apple can have full-color and full-resolution boot sequences and boot menu (what you see when you hold down option).
Therefore, whatever ends up happening, all PC video cards on a mac (if they run at all) will have a black screen until the OS loads the driver. This hand-off between the video card's ROM driver and the OS driver occurs just before the login screen. (2)
