I just checked again, they've updated the source.  Grab the PPC 
xilinx_intc driver into your current working dir with this command:

rsync -avz --delete 
source.mvista.com::linuxppc_2_4_devel/arch/ppc/kernel/xilinx_pic.c .

and see what they've done.  Basically if it's a level sensitive 
interrupt they ack after, else they ack immediately.  Smells like a hack 
to me.
