"make config" with current kernel
 

I am trying to chang me kernel settings, but im not sure how to do it. I am trying to turn on loadable module support.
Thanks for any help.

redhat and most distros will definitely already contain loadable module support

but if you need to check, just do
su
cd /usr/src/linux (or /usr/src/linux-linuxversion)
make menuconfig

check the category "general setup" or one of the categories near the top for loadable module support
