And for > > speed. going through a module is slower than not. Err, once the module is loaded, the speed is identical. However, a module does use marginally more memory (a module's code segment takes up pages corresponding to VM pages, while a compiled-in driver takes up exactly how much space it needs). Thus an average module will waste PAGE_SIZE/2 bytes (where PAGE_SIZE depends on what MMU you're using and how the Linux port to that particular architecture uses that MMU). The idea of compiling in those drivers that you know you'll need can save a few K. For those of us with 64MB of RAM, that's not a good enough reason to give up the flexibility of modules. For folks using an 8M machine as a router, that's a different story.
