128KiB for NOLO Bootloader
384KiB for Config partition
256KiB for Log partition
2MiB for Kernel partition
2MiB for InitRD partition (teorically not used on N900, wasted space ??)
251MiB for rootFS partition (the only, I think, with UBIFS)

To be fair, I think it's not that they aren't willing to change, the multiboot process actually does some setup/initializing prior to android's boot sequence that nitdroid depends on. uBoot doesn't do that setup, so the nitdroid kernel/bootup process would need to be adapted to work in that state. And probably I would guess working on that adaptation, when multiboot already works and is user-friendly, is not as important right now as working on things like making phone calls work...
So an initrd is needed to boot.
Multiboot uses the rootFS as a big InitRD.
It boots from rootFS, loads the necessary kernel's modules, mounts the nitdroid's partition and then chroots to it
Create an InitRD (or ramdisk) image or recompile the nitdroid's kernel with EXT3 support built-in and probably you could start Nitdroid directly with u-boot
PS
Since Multiboot uses rootFS as initial boot device, it can't be used with kernels (i.e. MeeGo) that cannot boot from rootFS (because they don't have UBIFS support statically compiled or because their default bootargs don't use rootFS)

I have tried to install v1.1 under multiboot with this my guide:
Unfortunately BackupMenu 1.1 doesn't start (the 0.62 was working instead).
The last message I see is "chrooting" then after some seconds N900 shutdown (watchdog ??)

- Download and install multiboot 0.2.11 and backupmenu-multiboot 1.1
- Download latest backupmenu package and copy it to MyDocs
- Open an xterm and become root user with
sudo gainroot - Remove backupmenu's old files with
rm /usr/share/backupmenu/* - Go to filesystem's root with
cd / - Extract backupmenu's new files with
dpkg-deb --fsys-tarfile /home/user/MyDocs/backupmenu_1.1-1_all.deb | tar xv ./usr/share/backupmenu/ - Add execution permissions with
chmod +x /usr/share/backupmenu/*
chmod +x /usr/share/backupmenu/.functions.sh.swp

Completely unchecked guessworking - isn't BackupMenu.item (located in /usr/share/backupmenu/ = location that you rm prior to updating) modified to suit multiboot?
Also, Fabry post reminds me of something. When I switched to ext4 for my home, I needed to manually edit backupmenu files to change "ext3" to ext4. no big deal, though, maybe it's possible to - without much time involved - to tweak backupmenu script such a way that they would work for both ext3 and ext4?

BackupMenu.item is in /etc/multiboot.d/ and not in /usr/share/backupmenu/ so rm doesn't delete it

Strange, I definitely have "BackupMenu.item" in /usr/share/backupmenu and its totally different file, compared to .item in /etc/multiboot.d/. that's why I pointed it to You, although I'm not sure if it's relevant, hence warnings about guessworking.

Files in /usr/share/backupmenu/ are the "active" files - they are the ones that actually do something.
All other files, the ones in /etc/ are just config/launcher files.
As far as why yours won't work, it's because you aren't running the postinst.sh script in the deb package. This script copies a rrquired binary(gnu tar) to my directory. Without it, it won't run.
Also, that runs my browser-launch-script for counting users and providing a readme.

Sorry, can't stop myself from posting that. Seriously thought, I think that You shall write info about it @ package description (and here in 1st post) - not that I think you're doing bad thing, but I stand on position that every tracing - even such harmless as this - should be 100% acknowledged to users.

BackupMenu.item is of course in /usr/share/backupmenu and it is deleted and then replaced by newer version
