The ascii art attempt failed. ;-)

Since the boards are pretty the same, I guess you can just compile
the u-boot-1.3.3 (please try release instead of -rc, to be sure),
and see if NAND will work. Maybe it will need really small code
modifications for your board though.

Otherwise it is hard to say where is problem is (maybe the problem in
the 1.1.4 nand core code, not in UPM setup?).

Also, you didn't mention what kind of chip the board is using.

Thanks,
