Hi Boudewijn,
I had a similar problem, couldn't boot anything from NAND(qi or uboot
the same). Jffs worked fine.
While trying different UBIFS distributions I have accidently flashed
kernel to where bootloader should be. Reflashed everything as it should
be, and the phone started to boot from NAND. 
The distrib was QtMoko v35.
I think there could be some wrong data or bad blocks somewhere that
were erased by flashing kernel to the wrong place. Or some bug was fixed
in qi or kernel. Cant check.
