Quake3/4 crash with 1.0-9640

[oc2k1]

I've installed the driver that's bundled with
NVPerfKit 2.1 Installer for 32-bit Linux (2006-09-11)
but now I can't play Quake 3 or Quake4 both games are crashing at startup. My quake3 version is modificated an use an Accumulationbuffer for Motionblur (may be or may be not important for this bug)

Try using 9625/9626 insted of 9640, because this one is actually *older* than those two.
