PMC card problem

Hi!
  I'm porting mvista linux2.1 on my motorola lopec mpc7410 board with a
zynx zx212 dual-port ethernet card on it.The problem is that the kernel
can't start up with the ethernet card on,while without it everything
is perfect.Since zx212 is compatible with 21143,I build the kernel
with the "tulip" option on.It should be no problem,but it happened.
It halts after "now booting the kernel". Zx212 is a PMC network card
with Intel 21143 and Intel PCI Bridge 21152. Through the bdi2000,
it seems that there are something wrong with "setup_arch",and maybe
"pciauto_bus_scan".But I'm not sure. Maybe you can help me.

The booting information outlined below :
