OK, JFFS2 aside then, let's focus on MTD core code.

How come hector was then able to write his JFFS2 partition ?

Is the old Freescale 2.6.35 GPMI NAND format compatible with the one after
applying this patchset?

Ok, does that mean that we need this patchset in U-Boot in order to properly
write JFFS2 onto GPMI NAND there? Is that the message you wanted to relay to us?
