Jonathan,
I haven't flashed Heads myself, but am passingly familiar with it
since I do basically the same thing on my hardware including an
X230 (and intend to recreate that on top of Guix, eventually).

I've tried adding the usual debug flags to the kernel command
line for troubleshooting (debug, higher LOGLEVEL, earlyprintk to
vga) with no change.
That won't help if there's nowhere to print to. From your
screenshot, you're not in VGA mode, for example. Is that
screenshot from within Heads? Which graphics driver is Heads
using at that point? Have you tried adding the same driver to the
initrd?
(initrd-modules (cons* "i915" %base-initrd-modules)))
It's also possible that Heads uses the Coreboot ‘simple’
framebuffer, for which you'll have to set at least the following
kernel options:
FB_SIMPLE=y
GOOGLE_FIRMWARE=y
GOOGLE_COREBOOT_TABLE=y
GOOGLE_FRAMEBUFFER_COREBOOT=y
[Google isn't even being coy about stealing credit for others'
work anymore.]
Unfortunately, that requires compiling a custom kernel.
Just some ideas,
