Description Ross Burton 2012-09-28 09:38:14 UTC 
It's entirely possible to end up with a valid image that doesn't start X because the server and drivers have different ABIs.  The package system can help avoid this by the xserver-xorg package providing names such as xorg-input-abi-16, and then the driver packages depending on those.

This will have to be implemented by the xorg-xserver package at build time writing the abi versions to staging, where they can be picked up driver builds and used in the dependencies.

For example, in Debian xserver-xorg generates and packages /usr/share/xserver-xorg/xinputdep which contains "xorg-input-abi-16, xserver-xorg-core (>= 2:1.12.3.901)".  Input drivers then add those dependencies to the package when they build.
