[drm] This hardware requires preliminary hardware support. See CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT, and/or modparam preliminary_hw_support
2015-10-05: I tried to boot Qubes R3.1-alpha (Qubes-R3.1-alpha1.1-x86_64-LIVE.iso) from a usb stick. It dumped me into the dracut emergency shell. Unfortunately, mouse and keyboard didn't work, so can't do much. Legacy USB support and CSM is "on" in UEFI. A second try also ends the same way. Perhaps Qunes doesn't grok the usb ports on this machine.
