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.
vgapci0: <VGA-compatible display> mem

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

I hope this helps.
