None of the major distros will be including XFree86 with the new license.
The licence, first announced on January 29 by XFree86 president David Dawes, is technically known as the 1.1 edition of the XFree86 license. License 1.1 was intended, according to Dawes' announcement, to "strengthen the 'except claim you wrote it' clause of the Project's licensing philosophy regarding binary distributions of XFree86."
Specifically, the license now requires that full credit be given in source and binary code to the XFree86 Project anytime the xlib files are used.
Developers have indicated on various mailing lists that such inclusion of credit would be logistically difficult to implement at this time, and in their opinion, such a license would be incompatible with the GNU General Public License (GPL).
