I still use the IMGSIZE=26214400 from your kexec wrapper for
Droid 4, which should be 25MB. With the updated .config my
image looks like this:

$ ls -lh arch/arm/boot/*Image
-rwxr-xr-x 1 sre sre  17M Jul 17 12:44 arch/arm/boot/Image
-rwxr-xr-x 1 sre sre 7.2M Jul 17 12:44 arch/arm/boot/zImage

Unfortunately I did not check size before I dropped the config
options. I don't think I removed 8M of config options, but who
knows.
