Default X crash on login in KDE4 with composite enabled - driver 185.18.08

With this xorg.conf
Code:
Section "Device"
        Identifier      "Configured Video Device"
        Driver          "nvidia"
EndSection

Section "Extensions"
        Option      "Composite"   "disable"
EndSection
I can login in X, no problems, no desktop effects (kde 4), direct rendering working.

with this instead:
Code:
Section "Device"
   Identifier "Device 0"
   Driver     "nvidia"
   Option     "IgnoreDisplayDevices"   "TV"
   Option     "Coolbits"               "1"
   Option     "AddARGBGLXVisuals"      "1"
   Option     "TripleBuffer"           "1"
#### For composite use... ####
   Option     "AllowGLXWithComposite"  "1"
   Option     "DisableGLXRootClipping" "1"
   Option     "DamageEvents"           "1"
   BoardName  "nVidia Corporation GeForce 8400 GS"
EndSection

Section "Extensions"
   Option      "Composite"   "enable"
EndSection
X seems to crash as soon as I login via kdm, coz the screen goes black and the kdm login screen shows up again.
In this situation, output of dmesg shows:
Code:
IRQ 18/nvidia: IRQF_DISABLED is not guaranteed on shared IRQs
IRQ 18/nvidia: IRQF_DISABLED is not guaranteed on shared IRQs
IRQ 18/nvidia: IRQF_DISABLED is not guaranteed on shared IRQs

I believe this is a known issue. If I recall correctly, an NVIDIA employee stated it will be corrected in future releases.

Edit: Here is a link to another thread about it:

Default Re: X crash on login in KDE4 with composite enabled - driver 185.18.08

Ubuntu Jaunty (Gnome) - nVidia 8800 GT

nVidia driver 185.18.08 crash if I switch Twinview displays or I change resolution/refresh.
I'm back to nVidia driver 185.18.04.
