Perhaps one of those modules [1] needing firmware? Note that Greg said, and re-iterated that it /could/ be due to that. It doesn't have to. Some external hardware wants its firmware loaded, and might refuse to talk to the kernel driver otherwise (or will appear in a "minimal", degraded variant). This applies to GPUs, too.
