Where do you pass erasesize ? Erasesize is an autodetected value inside 
nand_scan() and _must not_ be modified.

Ooops !

It fails as kmalloc max. allocation size is 128K. 

But why does anything there try to allocate 544K for a buffer ?????  What did 
you change in nand_bbt.c ? What's the bbt structure you pass to 
nand_scan_bbt ?

Can you send me your driver code so I can have a look ?
