Interrupt mapping for MPC8541

We are developing a custom board mother board based on
MPC8541 processor trying to run with Linux 2.6.11. The custom board has
hardwire the
interrupt lines for PCI peripherals with specific interrupt number for
each peripheral. 
The MPC8541 has on Ethernet chip which during boot process the Linux
kernel assign 
interrupt number 96 to it. Unfortunately one of our PCI peripheral that
is hardwire need that
interrupt number and this causes conflict. 
Is there anyway we can avoid reserving this interrupt number so kernel
does not assign it unless it is asked specifically?
