Ok, so I tried with the vesa X.org driver and it never had the blank screen problem (so far). There were some screen distortions on mode change but no blank screen. I noticed that when using the vesa X.org driver the i915 kernel module didn't load. I think we're getting closer! It seems like it's not a kernel regression but a bug in the intel Xorg driver. Or maybe an interaction between the i915 DRM kernel module (>=2.6.25) and the intel X.org driver, because it only happens with the 2.6.25 kernel, and I'd think if it was only an X driver bug, then it should've happened on other kernel versions.
