Browsing reports about similar problems I have found suggestion to use i915.modeset=1 i915.powersave=0 unfortunately this also leads to black screen and freeze of machine. In my laptop machine (chipset 945GM with agpgart and intel_agp and i915 compiled as modules), when I reload i915 with modeset=1 it causes immediate black screen and freeze (the value of powersave parameter does not change the behaviour of my system). I have also found some info that the problem may be related to detection of lid switch (in laptop) - I tried to press and release the lid switch in my laptop machine - this switched the backlight on, but system was still frozen and unaccessible.
