You'll probably find it works if you just hack cfi_probe to invoke 
cfi_cmdset_0001 instead. See the list archives - this came up quite 
recently.

You need to handle multiple chips interleaved on a wide bus anyway. 

Numchips isn't too difficult and by doing it at the command set level we 
eliminate the need for external wrapper functions which make multiple calls 
to the single-chip version of the access function.
