That's nice (thanks again Gerhard), because, then, I was able to use
Debian's kernel, which has network and sound working.
For some reason, with my own kernel I don't have any of these working,
despite the configuration not having anything remarkable of difference.

With that option (and it taking effect), the colors of regular applications
(like Emacs) are distorted (like an endian error).

glxgears also have the same kind of striped output and, then, it locks up,
as before. :-( But the machine is still working and I can access it via the
network, which is the important bit. See below.

You hit the nail in the head. Here.

Despite the test succeeding, with actual use I got this lovely thing:
