I've i945. Problem appears because of PCI-Express video? as i've found fromthis maillist. If I use
for exmaple "kldload acpi_video", then there no AGP driver device assosiasion in "pciconf -lv", and no /dev/agpgart, no DRI.
I use only "kldload i915" and agpgart device appears, and agp driver became assotioated with video device. I mean "device agp" or "kldload agp" have take place before i915 + drm modules loaded.
