The one I can think of that is capable of taking EISA/ISA cards but has
differently IRQ plumbing arrangements is PA-RISC, and they do exactly
this.

Beyond that it probably doesn't come up except in the weird world of PCI
legacy compatibility for legacy IDE and VGA vertical interrupt routing.
In those cases we fix up the PCI config space so the platform in turn can
do proper IRQ plumbing.
