Is this MAC address correct?

So the innards of that box (plastic case) are not different to the older
revision (metal case).
So the first problem for you is, that I recently "fixed" an
big/little-endian issue for the flexcop-chip when running on
big-endian-hardware such as PPC.
Unfortunately this change is apparently wrong when operating an
flexcop-based USB box on a PPC. (the first problem from above) The
big-endian-issue is checked only at compile-time and because the PCI and
the USB driver are using the same flexcop-chip-driver. It's working
correctly for the PCI card on PPC...
In the meantime I learnt that the flexcop-register-stuff I wrote for the
flexcop-chips is not optimal... especially when looking at the
endian-issues that can take place.
And it gets worse: I don't even have an idea how to fix it for you,
without breaking support for the PCI card on PPC.
You can try editing manually the flexcop-reg.h
and substitute this line
and try again.
