I've tested with
Section "Device"
	Identifier  "Card0"
	Driver      "vesa"
	Card        "** NVIDIA (generic)                   [nv]"
	Option	    "AccelMethod" "EXA"
EndSection
in xorg.conf file and all KDE4 works like a charm.. faster than I've even seen 
it so forget what I said before... the problem is not 50% nvidia and 50% kde, 
the problem seems 99% nvidia related.
I hope this will get repaired soon, since it is a blockstopper for kde 4.

B.T.W. I'm sorry to make noise, but this is really really fast with this 
config (but no 3D acceleration though :( )
