Bo185 the GM L92 based vehicle's do have DOD, its name is actually Active Fuel Management.
The L92 in the GMC Yukon Denali does not have VVT (Cam Phaser) and is only rated to 380hp.
The L92 in the Caddy has VVT and is rated to 408hp.
The Vortec Max in the 07 silverado is the L76.
Ironicly the Chevy Tahoe doesn't offer anything larger then the 5.3L Iron Block, but the TrailBlazer SS comes with the LS2???
The L92 shortblocks that are being built just plug the feeds to the solinoids and use the LS1/LS2/LS7 style lifters.
Now I liked DOD over AFM.
I'm guessing someone in GM's upper management thought having the same designation as the department of defense was a bad idea.

From what I have seen and heard the componets are installed in the L92 they just aren't using it yet. They seem to be having problems with the Active Fuel Management (DOD) and the 6L80E trans. working together.

L76 per Chevrolet web site.
Vortec MAX 6.0L V8 engine features:
* Variable Valve Timing (VVT) technology that optimizes combustion, enhances low-end torque and high-end power, promotes fuel efficiency, and helps lower emissions
