PCI serials shouldn't collide with legacy ones - PCI has different IO
Space.
Many boards don't disable interfaces completely - I wouldn't be suprised
if just the irq was dropped.
You need a different driver for your PCI one - e.g. puc.
The modem coild also be something proprietary for which there is no
driver available.

Why do you expect anything usefull by accessing half working hardware?
