You could check in drivers/mtd/nand/nand_ids.c and see if your flash chip, 
or indeed any chip with that page size is listed there. Even if it is, 
there could still be a bug of course.

I seem to remember some kernel of similar vintage failing with large-page 
flash chips because the driver tried to kmalloc a buffer the size of a 
block, which failed for chips with 128 KiB blocks, because of limitations 
of the amount of memory that could allocated in one go with kmalloc.
