"While development efforts within the X.Org community are now
ramping up for the release of X Server 1.9 that should arrive in
August, there is an ongoing discussion concerning a planned
long-term change for the X Server: pulling the drivers back in.
"With X.Org came the modularization of drivers compared to
XFree86, which allow drivers to be built independently of the X
Server. However, it was proposed a few months back that with X
Server 1.10 that the drivers get pulled back into the X Server.
This would result in X.Org becoming a more monolithic package, but
would allow driver developers to more easily break the API/ABI and
other invasive changes."
