I'll try. But I need a patch from samsung (my board is Samsung SMDK2410 with
ARM920T) and I don't know whether the current patch works fine with a newer
kernel.

You are right. It was my mistake. I've correctly (I believe) patched the
kernel.
But next, I tried to recompile the kernel and got this message:

drivers/mtd/mtdlink.o: In function `put_mtd_device':
drivers/mtd/mtdlink.o(.text+0x4b8): undefined reference to `BUG_ON'
drivers/mtd/mtdlink.o(.text+0x4b8): relocation truncated to fit: R_ARM_PC24
BUG_ON
drivers/mtd/mtdlink.o: In function `nand_scan':
drivers/mtd/mtdlink.o(.text+0x406c): undefined reference to `nand_flash_ids'
drivers/mtd/mtdlink.o(.text+0x4070): undefined reference to `nand_manuf_ids'
make: *** [vmlinux] Error 1
[root@Lab linux]#

Moreover after the patchin.sh was applied, the menuconfig has changed.
I cannot see anymore the s3c2410 nand driver. What happened to it?
