with the new boot system  you can just format the heads/cylinders as you like
and ignore  as long as your x-loader in NAND is intact. And even then, I
suggest to follow the GTA04 documentation and not some inofficial beagle
The new boot system scans for the first kernel it finds in any of the 4 ext2/3/4 partitions.
Therefore the first partition not even needs to be FAT and you can have 4 ext partitions.
Unfortunately I did not yet find the time to write a full documentation.
