Good catch, Thomas.

Looks like a miscue on my part - although the timestamp on the vmlinuz in /boot
matched the one in arch/x86/boot/bzImage, the file size matched the one left
at the end of that bisect from last time. Looks like I managed to cd into the
wrong /usr/src/linux-* when I copied the bzImage to /boot.

Sorry for the inconvenience.
