Update the XFree86 3.3.6 port to:

• contain the released Rage128 patch (but unfortunately this does not solve all problems with this card under FreeBSD)
• fix the release date "January 1999" --> "January 2000"
• make it possible to build a package

	  (PLIST problem: lib/X11/doc/BetaReport is not installed with 3.3.6)
