^^^^^^^^^^^^^ This is the part #. You can ignore the rest of the stuff.
Go to www.intel.com and download the datasheet on this part and see if it is a
CFI compatable NOR flash or not.

If not CFI, but is NOR, then try to use the JDEC module, rather than the CFI
module. If Not NOR (i.e. if NAND)
then I don't know.

Hope this helps.

P.S. This is really a MTD issue and you will probably have more luck posting
to that list. I've CC to that list if you
need the email.
