I Look at the PIRQ code.  The code that I looked at was the stuff 
included with HAVE_PIRQ_TABLE=1 and it most definintly _copies_ the 
table to 0xf0000.  So for this code to work shadowing must be setup.

Unless there is some linker magic going on that actually locates the 
structure at that location in the ROM as well then PIRQ stuff will not 
work w/o shadowing.

On my build the table is located in the ROM image and will show up at 
0xf2e29.  Linux searches for the table from 0xf0000 to 0x100000 but only 
at mutiples of 0x0f.  So linux will not find this table.

There must be some sort of ELF section alignment thats missing in the 
linking of irq_tables.o
