Right, the display is a Samsung full-HD device.
The graphics HW is shown below with some additional data about
the system.

         A snippet from the beginning of boot time dmesg to show
         the sort of PowerPC system I have been using...

         A lot of useless stuff has been deleted here, but below are
         the dmesg lines for the 2 graphics devices which are present
         in the system.

         Here is what "pciconf -lv" has to say about those graphics 
devices...

I hope this helps.
