I added the line to my xorg file.  Just in case.  ;-)

I logged into my test user with a clean .kde4 directory.  It took a few 
minutes but it did lock up when I opened Konsole again.  I booted my USB 
stick again and did a check on the file systems.  It says everything is 
fine but I'm doing a fresh install on my spare drive.  It was a drive 
that I got along with my video card.  Anyway, I'm going to test the new 
drive here in a little while and see if it still locks up or what.  I 
copied over some files in /etc and my world file plus distfiles.  I'm 
trying not to copy over any more than I have to.
