I'm running the latest linuxppc-2.4 branch. I'm not using the MPC8540ADS
board, the board I am using has an Intel LXT971A PHY attached to the
FCC. I've added support for that physical layer to
drivers/gianfar_phys.c. I'm guessing something is wrong with that code
that is making it go so slow, but I have been unable to pinpoint what
might be wrong.

I've noticed that the interrupts for the FCC come in at a very very slow
pace, that is the only thing I have really noticed that is odd. I've
also tried changing the priority of the interrupt via the IIVPR register
for the FCC with no results. I can't think of anything else I can
investigate, unless you have any ideas?
