(From commit log as I have no imagination whatsoever to come up with something 
different:)
Thanks to kris and krion for running several cluster test builds,
maintainers of GNOME for prompt responses, portmgr for postponing ports
freeze for this update, testers on FreeBSD-X11@ list and others that I
might have mised here.

Also included:
- fix for ATI Mobility on Dell Inspiron 7500 (obtained from Marc Aurele La
  France; obtained and tested by julian)
- fix for kbd driver on Sparc64 (tested by Aaron Dudek, Michael G. Jung and
  Matthias Muthmann), which still appears to have problems with some
  keyboards - so
- fix for kbd driver on PC98 (reported and tested by NAKAJI Hiroyuki; PR
  ports/77217)
- fix for i810 on HP D530 (obtained from Egbert Eich; obtained and tested
  by Anders Nor Berle; PR ports/74757)

Have fun!
