All I know is libpvrPVR2D_X11WSEGL OpenGLES2 was being used in the 4.05 version but no longer exists in this newer version. The only version of libpvrPVR2D_X11WSEGL that exist is for OpenVG. I was told by the graphics team that libpvrPVR2D_X11WSEGL is deprecated and libpvrPVR2D_DRIWSEGL should be used instead. Is this a non issue?

Here's my limited understanding of the wsegl stuff:

X11wsegl is a 'dumb' way to make it work with x11. It will tell X11 the rect coordinates to draw a window border and nothing more. The rendering still happens to the framebuffer. No context locking, nothing.
Driwsegl uses DRI for rendering and need a proper Xorg module to work, it features locking and stuff so you can have multiple clients. 

Roger Monk had it working a few months ago on omap4, but I don't know what he had to do to make it work. I hope it is as simple as rebuilding the sgxkernel modules with SUPPORT_XORG=1 (actually dri) and installing the binary Xorg module.
