pushing Ubuntu changes to xorg.git

	Hi!

  I've just pushed five changes from Ubuntu xorg to alioth xorg.git.. 
Hopefully they all are useful, and if not, easily reverted :)

There are a bunch of other changes that could prove useful. I'll try to 
either put them in a git branch or otherwise separately available for a 
review. I've done that for an older version back in March, and they are 
still available here:

I'm not sure how radically the postinst is going to change in the future, 
so maybe some of the quirks could be dropped now.

comments?
