Answer 1

To answer your original questions:
Misbah wrote:If the module is preloaded will it work that way?
Yes. What I do is compile my own kernel with just the modules I need built into the kernel itself. You'll need to do some research into what modules you need for certain tasks though.

Test it and find out. It's not always consistant across everyone's hardware/system.
Misbah wrote:If i add a module into modules=, i dont have to add the modules it calls on right? It will load those automatically? ie) I just have to add rt2500pci and it will call on rt2x00pci and rt2x00lib itself right? And those in turn will call on other modules that it uses?
Dependencies are called automatically.

How long does module loading take at the moment? If it's not a completely unreasonable time, I would say you are going to gain a negligable boot speed increase comparable to the effort involved. If you are really wanting to pursue a quicker bootspeed, then compiling your own custom kernel is the way to go. Even then, if bootspeed from GRUB to login prompt is less than 30seconds, gains are pretty much negligable.
