So why, for example, if you say need a NIC driver that requires miibus, do you have to specify loading of miibus..this is really at the bottom of my question. Shouldn't a module dependency system load the required drivers first ? The reason this popped up in my mind, as I think I mentioned, is that the port drm-kmod, for DRI on certain cards, is meaningless without the "agp" module being loaded. So why doesn't kldload (I suppose I mean the program rather than the system call) work all this out ?
