I load drm.ko & i915.ko before Just to make sure we talk about the same things: Did you configure the X server to use 3D (dri and glx in the modules section, dri section in the X11 config, dri device visible in devfs)? xdriinfo shows some valid hardware acceleration? If yes, I definitively have to test the 3D part again with my radeon (with a normal jail and with a vimage jail in case the normal jail fails). > starting the vimage jail. X sees it and uses it.

On a plus side > my laptop is running cooler and faster now. If you didn't had loaded i915.ko before, you have at least 2D accel now, and probably the power management of the chip got activated too.
