It's on the PCI bus. It needs to be an "open collector" type.
Sharing or not is really not a software issue! The only
kind of hardware problem that could cause "shared interrupt"
line problems is the designer fails to provide the correct
kind of interface driver. In that case, just "dead-bug" a
FET (or two) on the board, near the connector, to convert
the driven bit to an open-collector (drain) bit.
