You can't have both agp_load="YES" in loader.conf and agp in your
kernel.  Remove it from loader.conf.

The hal module is not needed for the DRI, generally.  I don't completely
understand how the DRI works with multihead Matrox.  I think you're
supposed to be able to do accelerated DRI on both heads with the mga_hal
module with one of the driver options, but I have never tested it.
