Thanks.  I reverted this kernel patch and confirm that the ULCD7
display works with systemd-gnome-image + task-xfce-base.  (It won't
auto login for some reason that I'm still investigating.)

What do you do to get the touchscreen working?  It doesn't even show
up in /dev/input, although the TSC2007 module's built into the kernel.
 The ESC image boot process showed:

[    3.318267] input: gpio-keys as /devices/platform/gpio-keys/input/input0
[    3.326477] TSC2007_init started
[    3.330566] input: TSC2007 Touchscreen as /devices/virtual/input/input1

but what I have now shows only the gpio-keys device.  Is there
something in uEnv.txt for this?  I"ve installed xinput and related
packages, but if the device doesn't show up there must be something
more fundamental wrong.
