The problem comes from closed-source X.org drivers, which only work
with a certain X.org driver ABI.

We have amd-catalyst, which depends on ABI 19:

package/amd-catalyst/Config.in: depends on BR2_PACKAGE_XSERVER_XORG_SERVER_VIDEODRV_ABI_19

And nvidia-tegra23, which depends on ABI 14:

package/nvidia-tegra23/Config.in:       depends on BR2_PACKAGE_XSERVER_XORG_SERVER_VIDEODRV_ABI_14

So if we want to remove older X.org versions, we have to see if newer
versions of those drivers are available, and perhaps coordinate with
the maintainers of those drivers.

Best regards,

Thomas
