Nand detect

[lp4u at inwind.it]

Hi, 
 
I've a s3c24210 board with BAST architecture, with 2 NAND on board. 
I've compiling the kernel 2.6.9-rc2 after patched it with: 
- patch-2.6.9-rc2-bk11 
- dm9k-rc2.patch 
- patchin (mtd 2004/09/19) 
- nand_multi1.diff 
 
Now, the board start with NFS e detect the NAND Flash; but boot output is unusual, infact is: 
 
 FTL driver: nftlcore.c $Revision: 1.96 $, nftlmount.c $Revision: 1.36 $

I don't get work with the NAND, why? 
MTD detect 5 devices, I've only 2 NAND. Why, occurs that? 
The proc/ is empty, there aren't device, why? 
Must I work with /dev/mtdN or /dev/mtdblockN? 
 
Thanks, 
Lorenzo
