Matt, did you have any luck with the test? Or is that still to do?

Thanks
Ben

so I talked to the Intel linux driver devs. The amount of system memory available as GPU memory to any application is completely dynamic, up to 2GB. The 256MB is just the aperture size. Steam's VRAM detection is completely broken, so it reporting 268.12MB or whatever is bogus and has no effect on performance. I don't think upping the aperture to 512MB would make any real difference in performance.

Aside from upgrade the kernel is there any way to improve video/graphics quality?

I am trying to use the device to steam stream, and on wired network I'm getting 30% fps loss.

I don't think you're asking the right question here - it's not an issue of video/graphics quality. It's either an issue of your network dropping packets, or the ChromeBox not being able to decode/process them quickly enough. Given that the CB can handle decoding a 60Mbps 1080p h.264 stream without breaking a sweat, I'm guessing this is either a network issue or something Steam-specific -- but definitely unrelated to my setup script or Kodi performance...
