----
I've recently updated Parabola, and X stop working. Some error with vesa driver (wich I've been using since few years from now).

Here is my Xorg.0.log

I ask in the Xorg list, and someone mention this:

Pretty sure this means your X server isn't running as root, and needs
to be.

I tried running X as root with no luck (although don't remember if
the specific error you point disapper. Could check it when got home.
The rest remains the same, I'm pretty sure about that.)

The other possibility I can think of is that your kernel has been
locked down hard enough that userspace isn't allowed to access I/O
ports. CONFIG_STRICT_DEVMEM might be guilty here. There's not been any
changes in either xserver 1.20 or vesa 2.4.0 that should cause this,
though.
