Well, certainly it is not a flashing problem.

The problem lives in the fiasco format of the last firmware (RX44). There's
some 0xff padding as a second header (the rest of headers are filled), my
flasher was just stopping because of unknown header, but now it is skipped
and works properly with all the current available images :)

I have also implemented a hw revision identification that can be forced
manually using the '-S' (sub-version) flag.

Now the piece names appends the version and sub-version strings. So no
dupped dump problem now. This fixes the problem of flashing parts of
the firmware of another sub-version (hw revision) of the device.

So, now I can say that 0xFFFF works properly for flashing directly fiasco
images.

I will release the 0.4 version this week after doing some work. I also plan
to build it for linux x86-32,64,arm and mips as deb and rpm. If I have some
spare time I can try to build it also on a powerpc macosx and w32, but help
is welcome :)

I want to make little code cleanup and make the output of the flasher messages
be more nice. Here's the current output after flashing my n810 with the
last firmware:

(0xFFFF -RF = Flash and reboot)
