Please check using the /dev/mtd0 device directly to see whether your writes 
are 'taking'. 

What 'map' driver are you using? I found that it didn't work for me on the 
iPAQ because I wasn't enabling the Vpp voltage during write cycles. Is this 
necessary on your targer?

Other than that, poke the author and/or look at the code yourself to see 
what's happening. What interleave/buswidth are you using?

Note to self: Must produce a proper bug report for Nico for the current
cfi_cmdset_0001 code, does doesn't work for me on 1x16 devices.
