I just tried that, and it did'nt work, I still have:

/ # cat /proc/mtd                                                                                                                                       
dev:    size   erasesize  name                                                                                                                          
mtd0: 01000000 00040000 "Physically mapped flash" 

I would really like it if my mtd1,mtd2, etc partitions were working...

Yeah, I did that, but I think CONFIG_MTD_CMDLINE_PARTS is giving me some kind 
of error.  When I do a "dmesg" I get this message

As you can see, cfi_cmdset_0002 gets itself disable.  I don't know if this is 
the cause of the problem ?!?

My init string is:
Linux/PPC load: console=ttyS0,9600 nfsroot=10.0.0.2:/exports/823_new 
ip=10.0.0.10 root=/dev/nfs 
mtdparts=physmap:512k(boot)ro,1M(zImage)ro,3M(ramdisk.gz)ro 

I've read many "how to" to get this right, but this is my "best" result.  I 
really don't know what to do next.  This problem is my main reason for 
getting on this mailing-list.  If you have an idea, I'm all ears :-)
