You do not recompile with modules - you either have functionality compiled into the kernel, or you have a modularized system. A mix is possible, of course: most hardware compiled into the kernel, some modules used.

When everything is compiled into the kernel, this is know as a monolithic kernel - useful for firewalls, routers and the like - modules are not supported because of possible security flaws.

Adding a module to the kernel is done with the modprobe command - it probes the hardware in order to find out if the module should be activated.

Generally, the kernel is bloated with support for hardware you do not have installed - compiling a new kernel usually will give you a much smaller kernel, resulting in faster boot, and better response time without having to sacrifice anything.
