drm_intel_bo for the KMS framebuffer with IvyBridge?

[Segovia, Benjamin]

Hello all,
Saying I want to play with an IvyBridge machine and the display when X is *not* running (I just opened /dev/dri/card0 from a terminal). Is there a simple way to get a drm_intel_bo for the terminal framebuffer such that I can brutally write into it? So, can I easily get its bo and its format (width, height, pitch, format, tiling)?
Cheers,
Ben
