Compile Linux Kernel w/ Dynamically (Un)loadable usbserial Module

view story

http://unix.stackexchange.com – I've attempted to install drivers for an FPGA device, but require that I remove the usbserial module. This happens to be impossible because usbserial is a built-in module. It was suggested that I compile a new kernel to make usbserial dynamically loadable and unloadable. I'm now trying to compile a custom kernel w/ Fedora. The guide being located here: http://fedoraproject.org/wiki/Building_a_custom_kernel At this moment I am using a GUI to set my kernel options, but I have no idea what options to select and deselect. Any advice would be greatly appreciated. (HowTos)
