What I do when faced with an X problem is to type "X" at a console prompt
and see if the bare X server starts up normally, i.e. with the black-and-
white background pattern and the x-cursor.  That at least will separate
the kde bugs from the xorg bugs.

I use startx, so doing this trick is easy for me.  If you use a display
manager like xdm,kdm, etc then you'll need to disable that temporarily
so you can boot to a console prompt.

BTW, did you generate a new xorg.conf after the upgrade?
