Ok, what other ARM+GPU could they have used that has an open GPU datasheet?
Well the ST one for starters.
I can't find an ST ARM with a GPU on ST's site http://www.st.com/internet/mcu/class/1734.jsp.
As far as I know, all of the ARMs with GPUs are locked down and under NDA. It's not a good situation but it's where we're at at the moment.
