Nice idea. I have entire disk encrypted and I keep my /boot on usb
stick (that I carry with me). With unencrypted /boot anyone can access
and modify kernel image and initramfs (for example, to intercept

Boot with 'break=y' in kernel commandline, this will drop you to shell
in initramfs. Check if you are able to access sd card. If not, try to
add some modules to initramfs and try again.
