As http://intellinuxgraphics.org/how_to_report_bug.html says:
3) For DRM kernel bug: Product=DRI. Component=DRM/Intel.

This is probably the correct category for Intel KMS bugs. But in fact it's not a big issue to file it there or the 2d component, as we have the same team to deal with these components.

For Intel specific changes in DRM, now Eric has a for-linus branch to directly for Linus to pull, not through David Airlie.

Yes, drm-intel-next is cutting-edge code for the next kernel cycle, while for-linus is for current kernel cycle.
