I'll have a look at this today, and see if I can make a boot bundle.
Some good news: I've been able to make a boot bundle from a
Narcissus-generated image - I used the 'minimal' image with all kernel
modules, dropbear and wireless-tools.
I made the following changes (I've used '---' marks to show the
beginning & end of inserted text):
1. Copy zImage from Narcissus rootfs /boot, to temporary dir for making
the boot bundle (cp boot/zImage-2.6.21-hh20 ../)
2. Set boot commandline in HaRET startup script (startup.txt.bootimage):
---
# initramfs-bootmenu HaRET script
# (c) 2007 Paul Sokolovsky
msgbox "Attention!" "This will boot Linux. All memory will be
overwritten and hard reset will be required to return to Windows Mobile.
You *MUST BACKUP* your data first. Continue booting (Cancel - quit to
make backup)?" 0x40031
if result == 2 exit
set cmdline "root=/dev/ram0 rootdelay=3
ip=192.168.2.202:192.168.2.200:192.168.2.200:255.255.255.0:ipaq:usb0
console=tty0 console=ttyS0,115200n8 rdinit=/sbin/init"

3. Edit initramfs /etc/fstab (removed the /home mountpoint to prevent
'empty flash' messages when /dev/mtdblock3 was mounted).
My initramfs /etc/fstab:
---
rootfs / auto defaults 1 1
proc /proc proc defaults 0 0
sys /sys sysfs defaults 0 0
/dev/hda1 /media/cf auto
defaults,noauto,noatime,exec,suid 0 0
tmpfs /var/volatile tmpfs mode=0755 0 0
tmpfs /dev/shm tmpfs mode=0777
0 0
tmpfs /media/ram tmpfs defaults 0 0
---
4. Edit initramfs /linuxrc - is it even required? No- I deleted it and
am using the standard /sbin/init. The initramfs is the final system and
we're not going to mount any 'main file system', so the minimal
Busybox init is not required (says I...).
5. Copy over wlan firmware (/lib/firmware doesn't exist;
/usr/lib/firmware doesn't either) to initramfs.
I copied the ACX firmware from my Ubuntu system, which might not be the
approved way of doing things - I have no way of knowing whether the
firmware would work with the hx4700 - a risky move, but it is working.
'Why didn't I use the SDG Systems WLAN firmware?' <shrug>
I copied the firmware over before making the initramfs.

The /lib/firmware/acx dir contains a number of revisions of ACX
firmware: 1.0.9, 1.9.8b, 2.3.1.31, and a 'default' dir with symlinks.
The hx4700 wants everything in /lib/firmware, so I made symlinks, as
shown above.
The acx startup (modprobe hx4700_acx ; modprobe acx debug=0) looks like
this:

I used a few scripts to make building the initramfs easier:
'make-bootbundle.py', you have already.
'make-initrd.sh' to make the initramfs ('initrd' should be 'initramfs',
maybe).
---
#!/bin/sh
# Execute this from the initrd root dir.
find . | sudo cpio -o -H newc | gzip -9 > ../initramfs.cpio.gz
---
'bootbundle.sh' calls make-bootbundle.py and names the bootbundle,
depending on the current date & time:
---
#!/bin/sh
# Run this to build the boot bundle
# L. 01-Nov-09
dt="`date +%d%m%y-%H%M%S`"
./make-bootbundle.py -o bootbundle-${dt}.exe haret-0.5.2.exe
zImage-2.6.21-hh20 initramfs.cpio.gz startup.txt.bootimage
---
Final notes: I may need to make more changes as there's sure to be
something that I've missed. As it is, this works, with a bit of
kludging around.
