The opencores PCI core _can_ be configured as a PCI HOST so in theory you
could use this to 'control' your PCI device. Check out Section 3.1.2. of
the PCI IP Core Specification document on opencores.
You will still need some sort of processor (unless you're a fan of coding
long state machines I suppose) to configure both the device's
configuration registers and the PCI core registers (though I suppose in a
known configuration the latter could be hard-wired at compilation time).
