That's not possible. You might disable a driver through loader variables (or kernel hints, or whatever), but the driver will still be present in the kernel image, so you cannot load a module that uses the same symbols. You will have to compile a kernel that does not include the driver. > I don't have the option of recompiling the kernel to exclude EM(4). Too bad. (Why don't you have that option?)
