After I removed this patch, I only could get output to the serial console. Does
this more than it appears to?

I found that plymouth forces text output at [1] because it cannot find the
default tty file.

There are two options I followed:

1) The default tty appers to be incorrectly set to tty1. I set it to tty0 to
get a text prompt on the console, but no graphics.

2) I can force graphical output by adding 'plymouth.graphical' on the kernel
command line.
