Anyone have more info on the Imagination BXE-4-32 GPU this is using, especially the availability of open-source Linux drivers?

A few months ago the Imagination site had a press release[0] about upstreaming graphics drivers to Linux which mentioned "B-Series" and "BXS-4-64" -- is that close enough to the BXE-4-32 that driver compatibility can be expected? I tried searching through the kernel source for 'BXS' and 'Imagination', but the only relevant hit was for some unrelated GMA 500 device from Intel that used licensed Imagination tech.

There have been posts on Phoronix about Imgtec drivers going into Linux/mesa occasionally, maybe the posts linked from them help you find the code in Linux/mesa.
