There are more than one.  By referring in the README to the "diskonchip" 
driver, I mean specifically the driver that is *called* "diskonchip". 
(The parenthesized hint in step one about doing "modprobe diskonchip" is 
intended to make this clear).

I'll have to check the menuconfig wording, but what it should say is to 
use the new DOC driver that works *with* the generic NAND device layer, 
rather than the old DOC driver(s) that doesn't.  If you enable NAND 
support, you'll find this new driver.

Should work fine; let me know if you need any more help.
