The banner, well, you know Linus' position on printing banners 8)
The rest seems superfluous:
int __init agp_init(void)
static int already_initialised=0;
already_initialised = 1;
memset(&agp_bridge, 0, sizeof(struct agp_bridge_data));
agp_bridge.type = NOT_SUPPORTED;
printk(KERN_INFO "Linux agpgart interface v%d.%d (c) Dave Jones\n",
