Just a hunch but you're loading the (builtin) modesetting driver, vesa
and fbdev and they're apparently all in the process of probing the HW
and then you run into a pciaccess segfault.

=> try uninstalling xf86-video-vesa and xf86-video-fbdevhw (so you'll
only use the modesetting driver since apparently modesetting itself
seems to work and you don't have xf86-video-ati installed) and see
whether that makes any difference.
Also see eg. https://bugs.freedesktop.org/show_bug.cgi?id=81678 and
google for pci_device_vgaarb_init - this seems a quite common issue...
