The uboot loader on the n900 kernel does'nt use a boot.scr
to load meego.
It searches for a uImage on the sdcard (only the third partition
and only if it is a FAT-partition).

What I tried:
- write the AI- sdcard image on a sdcard
- changed the type of the third partition from swapt to FAT
- copy all files from the first partition to the third
- reboot the device
Now, if you let the uboot timer timeout, it tries to load the uimage
from the sdcard.
It can load the kernel (2.6.32)
But starting the kernel fails (the device just turns off).
