On two of my boxes, the AGP shares IRQs with the third PCI slot, the
fourth PCI slot is shared with the first ISA slot.  It's a tangled web.

[On two other boxes, though, the AGP and first PCI are shared as you
describe.  I can also note that a lot of problems with IRQ sharing on the
PCI bus that I've had in the past with NICs have gone away with the 
2.4.0 kernels.  PCI irq sharing is part of the new kernel.  In the past,
irq sharing was only extended to the ISA slots, so I'm pretty pleased.]
