I've just build a new kernel and noticed it's fixed in current Linux
tree. Since -rc4 still had this bug, it was very quick to bisect this,
and the fix was this commit:


commit efc2924e733631a64c0afed8dbba2741d186998c
Author: Keith Packard <keithp@...thp.com>

    drm/i915: Call intel_enable_plane from i9xx_crtc_mode_set (again)

    This change got placed in the ironlake path instead of the 9xx path
    during a recent code shuffle.

Does it make sense? Do you still want the register dumps or they
aren't needed anymore?
