1st problem.

Is this MAC address correct?

2nd problem.

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
     #include "flexcop_ibi_value_be.h"
     #include "flexcop_ibi_value_le.h"
and try again.
