Still getting hangs with Xorg 7.5

[David Johnson]

So far things seem to be working. I added the WITHOUT_NOUVEAU variable and 
updated the dependent ports. As a side effect, all those ports are now marked 
as '>' in portversion. I'm hoping that won't cause any problems.

The actual culprit seemed to be EXAVSync in xorg.conf. I added that over a 
year ago to get KDE desktop effects working. Now that I took it out the hangs 
stop, but KDE desktop effects are now unavailable.

Thanks for the help.
