It's still there. Even with atombios, there is still a bunch of DCE
specific programming required (page flips, interrupts, hotplug,
watermarks, LUTs, cursors, etc.).  DC also adds support for a bunch of
new features that are were not supported by either atombios or the old
modesetting code (regamma/CTM, DP/HDMI audio, dchub programming for
display buffers in system memory for APUs, etc.).
