I think the problem is that AMD is assigning device-IDs of more than 16-bits. Anyhow, both AM29BDS643D and AM29DL640G supports CFI, so I would like to remove support for them in amd_flash.c (patch below) to avoid problems. OK to commit? /Jonas PS. Would this patch ever find it's way into Linux 2.4 or just Linux 2.6?
