IIRC, the 8259a was the interrupt controller back in the days when pc's
were fast at 8 Mhz, and the AT was really only for cpu intensive work.
The XT had one, and the AT had 2 by feeding one into irq2, hence giving
you 16 interrupts.
They may be a few gates on some huge fpga chip today, or the report may
refer to whatever X thinks is the interrupt controller. Anything that
makes it shut up should be ok. Have you anything hanging on the parallel
port? That's usually irq 7 but you can find out with
and see what has irq 7. Make it shut up or go to sleep and then look.
