i915 is a graphics driver in the _kernel_ for intel GPUs only. Since a VM doesn't have intel graphics card loading the driver has no effect.
Your best bet is to try and use scfb or vesa _xorg_ drivers. Install xf86-video-scfb and xf86-video-vesa packages and try running Xorg.
I've tested in a QEMU VM and it works without any extra configuration. Hope this helps.
