This is the property of the cards, *not* the bus. The ISA bus
has no issue with shared IRQs (though it is possible to load so many
devices on an IRQ as to cause a voltage drop, and make IRQ delivery
interesting (random), but normally only happens with old bad designed
hardware, and lots of it.
The normal PC/104 or PC/104+ board is of a much higher quality
than general PC trash, and often supports much more (such as shared
IRQ operations).
