Or vice versa? modprobe -n -v module_name will show you what modules will be loaded in what order so that any dependancies in "module_name" are handled properly. > Ditto, is there something there that tells the kernel that this > should be loaded when /dev/ttyS0 is touched?

But please realize, that's the "old style" way of loading modules, and is not recommended. It's because the major:minor does not describe a driver properly anymore, with the different types of serial, usb, and other drivers.
