Not really. We share interrupts when we have a cardbus bridge.
Sharing generally works.
However, you can use ISA interrupts. See the oldcard man page for
details:
hw.pcic.intr_path
Should PCI pcic devices route interrupts via ISA or PCI. A value
of 1 means route via ISA. A value of 2 means route via PCI.
This is ignored for the ISA device. Many older laptops do not
have PCI BIOS implementations that FreeBSD can use to route
interrupts properly. These laptops may need to set this to 1 and
hw.pcic.irq to a value (or 0 for polling). The default is 2.

: obvious, let me know :)
You are missing something. First, interrupts can be shared. Second,
if you have issues with PCI interrupts, you can route via ISA
interrupts.
