Yes, and yes.  That step is called modules. You compile your kernel with 
the option to use modules and then you compile modules for what you need, 
eg. filesystems, sound cards, NICs, etc. Those modules can then be 
dynamically loaded and unloaded as needed. They first appeared in the 
1.2.xx kernels, so they are getting pretty robust.
