I guess the most misleading may be the definition of location where the second-level kernel is stored on device.

Excerpt from my config:
Code:
# The first OS is usually Nitdroid.
# This section lists the Nitdroid specific switches and kernels
G_OS1_NUM=3
G_OS1_AUTOBOOT=0
G_OS1_PARTITION=5
G_OS1_NAME="Nitdroid"
G_OS1_1_LABEL="E-yes Nitdroid kernel -
 zImage_pr13"
G_OS1_1_FILE="/boot/Nitdroid/boot/zImage_pr13"
#G_OS1_1_FILE="/boot/Harmattan/boot/zImage_pr13"

G_OS1_2_LABEL="E-yes Nitdroid kernel, L2 cache fix -
 zImage_pr13-l2fix"
G_OS1_2_FILE="/boot/Nitdroid/boot/zImage_pr13-l2fix"
#G_OS1_2_FILE="/boot/Harmattan/boot/zImage_pr13-l2fix"
G_OS1_3_LABEL="E-yes Nitdroid kernel, ADB/USB -
 zImage_pr13-adb_usb"
G_OS1_3_FILE="/boot/Nitdroid/boot/zImage_pr13-adb_usb"
#G_OS1_3_FILE="/boot/Harmattan/boot/zImage_pr13-adb_usb"
G_OS1_4_LABEL=""
Nitdroid base system is located on my device on partition #5 (G_OS1_PARTITION).
The kernel (second-level, to-be-booted) may be where ever you like.
For convenience juiceme created links (named after the definition of G_OS1_NAME) on first-level system under /boot:
so /boot/Nitdroid defines /dev/mmcblk0p5

In my case the kernel is on
/dev/mmcblk0p5/boot/
see
G_OS1_2_FILE="/boot/Nitdroid/boot/zImage_pr13-l2fix"

but in former times I had in on partition #2:
G_OS2_PARTITION=2
G_OS2_NAME="Harmattan"
#G_OS1_2_FILE="/boot/Harmattan/boot/zImage_pr13-l2fix"
