Thanks for that, I'll see if loading modules with -k still works in
2.6.x.

I'd have thought that hotplugging i.e. plug in an USB device in this
case would load the modules as and when required.

If the interface is up, then it shouldn't have to be unloaded, I think.
I know I could just hack my initrds to remove any modules that I don't
want loaded at bootup but surely... :-D
