As I noted in my earlier email, I did need to do this on the 5282.
My code looks like this (NOTE: ON 5282!)

     /* We have to set up the edge port module to source interrupts  
from the IRQ line */
     *MCF5282_EPORT_EPIER = 0xFE;   // bit #7; enable interrupts on  
IRQ 7
     *(u32 *)(MCF5282_INTC0+MCFINTC_IMRL) &= ~0x00000080; // unmask  
IRQ7 interrupt

HTH.
