You have that under /proc
Note that PCI bus _IS_ supposed to allow to devices to occupy
the same IRQ (there is arbitration _if needed_, i.e. if either
of the devices indicates that it _CAN'T_ share a resource,
which would probably be the case for either modem or ethernet,
because of timing considerations).
Besides, did you consider that it might _NOT_ be the IRQ,
but also a possible I/O (including memory mapped I/O) port
or address, that could cause the conflict, and/or confuse
the driver because the wrong device would answer ?
The PCI arbitration is supposed to resolve this too, but
maybe the devices _CAN'T_ use any other address, in which
case you are screwed ...
