Default. Can be removed.

Here I preconfigured screen saving.

That's from the times of HAL. If your Xorg is not built with HAL (it's 
not by default now) you can omit that.

That was debugging. You don't need it as on filesystems like ZFS this 
makes Xorg extra slow writing logs.

This is needed probably, it's not default. But I don't know whether you 
need it or not. :)

default and DRI changed startup.

`ati` is a wrapper around `radeon`, `r128` and `mach64`. Anyway the 
latter two are from previous epoch by now.

And yes, I have AMD Radeon HD 7560D (part of AMD A8-5500 APU).

Sphinx of black quartz judge my vow.
