-intel should work.

will prevent the crash, as would fixing -modesetting not to invoke
DRI2CloseScreen if it DRI2OpenScreen didn't succeed which is how it is normally
handled.

To fix DRI2OpenScreen, you need to add the pci-ids to
hw/xfree86/dri2/pci_ids/pci_id_driver_map.h for -modesetting support.
