"Unloading" means that this module is not loaded at all because it is
not found.  If you look at 'xorg-configuration-file' in (gnu services
xorg)¹, you'll see that there is no ModulePath line for
'xf86-video-qxl'.  Moreover, this module is not even packaged :-)

If I understand it right, this qxl module is
<https://www.x.org/releases/individual/driver/xf86-video-qxl-0.1.4.tar.bz2>.
If it's just a usual X video driver, it shouldn't be hard to package it
– it would be very similar to 'xf86-video-vesa', 'xf86-video-nouveau',
and other video driver packages in (gnu packages xorg) module².

Patches welcome :-)
