File u_Refuse-to-run-on-machines-with-simpledrmfb-too.patch of Package xf86-video-vesa

From 05aa4057d9369165f4f49b5dcc9064b4bfdfe9e5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Refuse to run on machines with simpledrmfb, too
References: bsc#1193539

simpledrm framebuffer takes over EFI and manages the graphics.
Running vesa driver on those would confuse the system and result in a
bad interaction.
Just bail out like efifb and other cases.
