384k + offset(fb0 in GTT) ~= 576k, the size of the VGA text console. My guess
is that the VGA planes are not being disabled and through them the BIOS is
obliterating our setup. One quick test would be

diff --git a/drivers/gpu/drm/i915/i915_gem_stolen.c

        if (ggtt->stolen_size == 0)
                return 0;
