+Subject: [PATCH] video: Allow to set pure 'text' mode in case of EFI
+
+Current code doesn't accept a pure text mode when booting
+from UEFI firmware on i386 platform, this will result in
+below error message even we already have 'set gfxpayload=text'
+configured: "no suitable video mode found". This often happens
+when we boot a VM which UEFI firmware doesn't include 'suitable'
+video modes.
