I've got a new Supermicro with Opterons; all its IRQs show up in the 
new style:

$ cat /proc/interrupts

The same is true on every Intel or AMD box in our server room. Of all 
the x86 Linux boxes on which I have accounts, I could only find XT-PIC 
interrupts on one: an older OptiPlex GX100 with an Intel 82801AA 
chipset I've got at home.
