nice idea.
one thought:
i don't know i am very relaxed with such things for i patch up my things that they suit my needs. in general uboot as is is fine and nice for dev and extras_devel is exactly the place where it belongs. i don't know if you want it to stay there or want to have it working for productive. if it is the latter, its rather to fix the problems.than to workaround
that is:
- rebase it to a more recent git
- apply the pending important patches from git(don't like that but in case of severe bugs...)
- see how to make watchdogsupport work,
- solve the mmc thing matan mentions
- create a menu(or adapt one) with some shortcuts.
- maybe have a look at the serial console with the maemo kernel issue ali mentions.
that way you get it somewhere towards a version that can be used for productive.

Why this patch is important (in my opinion): MeeGo drains battery very fast, so if maemo or nitdroid suddenly reboots and SD card is inserted, MeeGo will be booted.
Patch solves problem. And decreases 'default' OS startup time.

mmc2 is even more problematic. It appears to work once after maemo, but If I boot from u-boot (by the command reset, or letting the watchdog boot), it won't recognize it again.
i can't see any problem rebooting other distros. i rsync a new kernel and it reboots just fine in the new kernel. and i do that a lot at the mom.
if i messed something up on the other hand and i have to take out the battery or such ... it is a whole other story. then weired things happen. it can't find the mmc and also maemo can't boot in this case sometimes...
another typical scenary is if i forgot about the battery and it shuts off.. after that(battery charged again...) it doesn't detect the mmc .. but this are all "unusual" cases ...

and if uboot is still there after that use force and flash the kernel you saved on your harddrive(must be the one you prev. installed via apt). and you are good.
(note that i said flash KERNEL not firmware and not emmc. that is: flasher -f -k kernel)
also note the order first use the most high level means of doing it and only if they are buggy and fail use brute force to achieve where that failed.

But I want multiboot back.
When I boot my N900 I first get U-boot
I do: run noloboot
Then I get multiboot and boot Power Kernel v45
How do I get rid of U-boot? :<
