[Assist] How can I compile a module for my kernel without having to recompile the whole kernel?

[Marc-Alexandre Espiaut]

Hi!

I'm using a laptop that needs the vt8623fb module and I don't know how
I can just compile the module alone since recompiling the whole kernel
(even if it's tweaked) takes way too much time on my machine.

I've lost 3days doing nothing but unsuccessful researches on the subject.
Now I spent something like 8~9hours compiling the kernel using the ABS
(https://wiki.archlinux.org/index.php/Kernels/Compilation/Arch_Build_System)
with the modules I needed and it just ended up creating a dummy empty
package (while saying that everything was done successfully).
Not to mention that patching the kernel from 3.2 to 3.2.7 just fails
miserably for no reason (?!) so I had to tweak the PKGBUILD to grab
the GNU/Linux Libre Kernel 3.2.7 directly.

It's seriously driving me mad and I'm starting to wonder if I just
doesn't have a IQ high enough to do all of theses things.

If anyone knows how to help me, you have all my attention. For now
I'll just prevent myself from smashing this computer on the floor.
Also, before anyone start to answer my problem by not answering it: I
don't want to use another distribution than Parabola. I have a problem
and I want to fix it.

Thank you all in advance for your answers,
