But...does this happen only when you have the second monitor on?
Or only adding the Twinview's options in xorg.conf?

And...just to add more info about this bug:
- It happens from time to time.
- It's also present with xorg 7.2(I reproduced it).
- It seems not having any relationship with the ipw card(My ipw doesn't share the IRQ with the nvidia).
- It's present with the newer kernels(I reroduced it with 2.6.20-rc4, with 2.6.21-rc1, with 2.6.20-beyond).
- It seems not having any relationship with CPU frequency scaling.
- It's related to Composite Managers(Beryl or Compiz): switching them off, it's not reproducible.
- It's making me become mad!


EDIT:
Can someone confirm it's not reproducible with Xgl instead of NvidiaGLX(AiGLX)?

A small tip I can do to stop the black flash(only temporally) is to change the screen frequency from "Auto" to "60Hz"(my video frequency) as shown in this image:
