    xf86-video-vesa: Refuse to run on UEFI machines
    
    Fix the following Xorg start failure on UEFI machines when using xf86-video-vesa
    driver (e.g. in qemu, when anaconda tries to start X):
    Xorg -br -logfile /tmp/X.log :1 vt7 -s 1440 -ac -nolisten tcp -dpi 96 -noreset
    ...
    (EE) Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices
    ...

+Subject: [PATCH] Refuse to run on UEFI machines
+
+No possible good can come of this.
+
+v2: Check for .../efi-framebuffer.0 ("is there an EFI framebuffer")
+instead of /sys/firmware/efi ("is this an EFI machine"). Suggested by
+Peter Jones.
