I don't want readonly ... my mistake ... I was
setting MTD_WRITEABLE vs. clearing it (duh!)

Here's the dump:
01fff0 90 87 2f 34 2e 16 d5 26 bc c0 4e d1 ff ff 19 85
...
03fff0 84 00 03 00 de 72 b0 79 ff ff ff ff 19 85 e0 02
05fff0 ff ff ff ff ff ff ff ff ff ff 19 85 e0 02 00 00

So ... the offsets are jacked.

I thought I used 131072. But based on the dump, I must have
fat-fingered 131071 :-(. I made a new image with -e 131072
and it looks good.

Thanks for the help!
