We currently treat the child_device_config as a simple struct, but this is not correct: new BDB versions change the meaning of some offsets, so the struct needs to be adjusted for each version. Since there are too many changes (today we're in version 170!), making a big versioned union would be too complicated, so child_device_config is now a union of 3 things: (i) a "raw" byte array that's safe to use anywhere; (ii) an "old" structure that's the one we've been using and should be safe to keep in the SDVO and TV code; and (iii) a "common" structure that should contain only fields that are common for all the known VBT versions.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
http://dri.freedesktop.org/wiki/Documentation
http://sourceforge.net/project/showfiles.php?group_id=387
http://dri.sourceforge.net/doc/
