You might want to make that NAND_ECC_HW_SYNDROME so that it's rejected on intialization, until some upgrade scheme is in place. Otherwise, the NAND driver will notice all the nastiness about how the 2.6.18 kernel's NAND driver is clobbering manufacturer bad block markers, ignore the current bad block table, and mark a lot of good blocks as bad (just because e.g. YAFFS2 wrote the blocks) ... which will make u-boot-unhappy ... prevent rebooting into the LSP 2.10 code on the flash chip ... repeat cycle ad nauseum.
