And I noticed that this can be easily added to patch 3, just like i915
driver does:

diff --git a/sound/hda/hdac_i915.c b/sound/hda/hdac_i915.c
index c9af022676c2..c48a014be7b4 100644
--- a/sound/hda/hdac_i915.c
+++ b/sound/hda/hdac_i915.c
@@ -361,6 +361,11 @@ int snd_hdac_i915_init(struct hdac_bus *bus)
if (WARN_ON(hdac_acomp))
return -EBUSY;

+#ifdef CONFIG_VGA_CONSOLE
+ if (vgacon_text_force())
+ return -ENODEV;
+#endif
+
if (!i915_gfx_present())
return -ENODEV;

It's hackish, but should work practically enough...
