M68360 ethernet troubles.

I've been using the 68360 (5v version) with the Motorola 68160
ethernet PHY for some time and recently started a board using
the 68360 (3.3v version) and AMD Am79C874 PHY.
The board comes up, then starts to initialize ethernet by calling
rtems_bsdnet_initialize_network(), but it never returns. When I
try to break (using CTRL-C in GDB), I'm notified that the processor
was stopped in _Thread_Idle_body. So, it doesn't appear that the
board has hung.
Hardware looks good. The PHY recognizes the ethernet cable and
shows receive activity information on the LEDs.
Being pretty ignorant about the ethernet driver, I don't exactly
know where to set breakpoints and what to check for. Can I get any
suggestions? Very similar code works on my 5v 68360 boards.
