That's ok.

This is what "request_module()" and "kmod" is all about. Once we probe the
hardware, the drievr itself can ask for more drivers.

I completely fail to see the arguments that have been brought up for drm
doing ugly things. The code should simply do

	drm_agp_head_t * head = inter_module_get("drm_agp");

	if (!head) {
		request_module("drm-agp");
		head = inter_module_get("drm_agp");
		if (!head)
			return -ENOAGP;
	}

and be done with it. THE ABOVE MAKES SENSE. The code says _exactly_ what
the module wants to do: it wants to find the AGP support, and if it cannot
find the AGP support it wants to load them.

The arguments about how the user should load things in some specific order
or whatever are complete crap. All the support is there, and whining about
it is not going to change my opinion in the least.
