Fanoush,
Just some feedback from a relatively new user here. When I received my n800 a few weeks ago I immediately flashed to the latest release OS2008. I was surprised at the lack of memory after adding just a few applications.
I searched for a solution and found the thread for using the SD card instead of the internal flash for OS2007. Then Sunday I successfully (i.e. no errors) completed instructions posted by Millhouse using your initfs_flasher. However I have had no luck booting from the internal slot using a partitioned 16GB card. The bootmenu is installed but selecting the second partition results in a failure every time. I have repeated the installation process to no avail.
I have read here in the forums that some have had success (albeit without access to WIFI???) and some like myself that have not. It is yet unclear to me after browsing the forums that this process is successful with the n800 and OS2008. This thread makes it sound that a custom bootmenu file may need to be in the initfs_flasher folder?
I have now also attempted to clone the OS to a 1GB Kingmax card. During the cloning process outlined by Millhouse many errors are being generated when taring the ./usr directory. These errors include "Cannot open: No such file or directory" or "Cannot open: Input Output error". If I let xterm run it takes about 12 hours for step 4 to stop. After that it won't complete step 5 and the file system on the second partition is corrupt. Xterm is also unresponsive at this point.
I decided to reflash OS2008 and start from scratch. But after repeating all the steps again, including installing the bootmenu, the results have been exactly the same. The new cloned 16GB will not boot and the seasoned 1GB card is still generating errors during cloning.

Trying to boot from MMC with a N810 and the latest OS2008 2.2007.50-2 I came across a few issues like mmcblk0 and mmcblk1 being swapped after booting (like vormund earlier). I finally got it right by swapping the devices in the initfs and also managed to prevent the root file system from being mounted over USB. A few pointers here.
For the MMC swapping problem, It may be a good idea to add specific initfs patches in the initfs flasher, but I do not know if this applies only to the N810, to OS2008 2.2007.50-2 or both...

p.s.- thanks for pointing out the osso-usb-mass-storage-enable.sh hack. I'd been looking for a way to disable the root fs mounting over usb...

The problem has certainly affected me. I tried the instructions given in the Millhouse thread and the Nuclear instructions, as recommended on the tablet hacker site. I will try the fixes mentioned above.

After installing init_flasher, I get the "Press Menu to activate boot menu" message for like a half a second and it immediately goes to booting from flash. No pressing of menu or any key seems to affect it.
Also my kernel flasher didn't work on n810 at all and nobody told me :-) Fixed this one too, it was just matter of adding RX-44 to the script.

I extracted the initfs.osso-RX-44.2007-49.tgz file from initfs_flasher and rewrote all of the /dev/mmcblk* nodes to match the root fs. Then I recreated the tgz file and ran initfs_flash.
Success! (mostly)
Now can boot to mmc and df shows the correct devices for the root filesystem (mmcblk1p2) and the external mmc (mmcblk1p1) (Yes, I'm booting to the external card. I'm hacking this thing a lot right now.. If I wear out the flash, I'd like to be able to replace it.)
However, df now shows that the /mnt/initfs device is /dev/mmcblk1p2 (or if booted from flash /dev/mtdblock4), and not /dev/root??? But /etc/mtab correctly shows /mnt/initfs as /dev/root in either case...
Interesting eh?
kernelpanic
As /dev/root is mounted read-only, I'm not too worried about it...
