[Disclaimer: All in my personal opinion]Oh my. They should do the same with the PowerVR2, there has been always a hombebrew Dreamcast scene and this would be terrific to have.
I could imagine that ARC-1 and Neon250 might be possible, but CLX2, which went into Dreamcast, I think had some (non-graphics?) logic added by Sega. I doubt IMG could release data without Sega's blessing.
