Please recommend IO Mapped Digital IO Card

I Have a requirement for a IO Mapped Digital IO card. It must be IO mapped so that I can talk directly to it from an intelligent device on a PCI bus, without involving the host.
I need to be able to find the IO Map and be able to control the state of IO lines by directly writing to IO ports on the PC.

Does the card need to appear in memory space (like most PCI cards) or IO space (mostly used by ISA)? Any NI PCI board appears in memory space, so you should be able to access it directly, just like system memory. But I am not aware of any DIO cards which use IO space (except ISA cards).
