I can take a look, I have a beagle sitting here on the desk.

Carsten made a kernel yesterday based on the DSS2 patch (thanks to Felipe!). It booted, had SGX working and even ran Xorg, but didn't output anything on screen.
Framebuffer or Xorg settings are wrong, I'll ask someone who knows to use their coffee break on it.

But anyway a huge step forward :-)
