Yes it will be, after you install a module, depmod is run which
generates a file called modules.dep . modules.dep lists all
dependencies for every module. These dependencies are then
automatically  loaded by modprobe when you try to load the actual
module.

First of all, is the code going to be used again after it is used
once? If not, then it is probably a better idea to include the kernel
module in an initial ram disk (initrd). This solves both the problems
- of loading a kernel module before the FS module on which it resides
is loaded, and at the same time not being forced to include the module
within the kernel itself.
