I have checked out PCI NE2000 driver:
LXR / The Linux Cross Reference
Do you mean using 'PCI_ANY_ID' ?

Code:

static DEFINE_PCI_DEVICE_TABLE(ne2k_pci_tbl) = {
        { 0x10ec, 0x8029, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_RealTek_RTL_8029 },
        { 0x1050, 0x0940, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Winbond_89C940 },
        { 0x11f6, 0x1401, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Compex_RL2000 },
        { 0x8e2e, 0x3000, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_KTI_ET32P2 },
        { 0x4a14, 0x5000, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_NetVin_NV5000SC },
        { 0x1106, 0x0926, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Via_86C926 },
        { 0x10bd, 0x0e34, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_SureCom_NE34 },
        { 0x1050, 0x5a5a, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Winbond_W89C940F },
        { 0x12c3, 0x0058, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Holtek_HT80232 },
        { 0x12c3, 0x5598, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Holtek_HT80229 },
        { 0x8c4a, 0x1980, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Winbond_89C940_8c4a },
        { 0, }

I tried myModule with 'PCI_ANY_ID'. It is visible in dmesg how myModule run .probe for few devices and failed trying to do 'ioremap' (inside .probe routine). Those are:

Code:

Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02)
Subsystem: Red Hat, Inc Qemu virtual machine
Flags: fast devsel

ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II]
Subsystem: Red Hat, Inc Qemu virtual machine
Flags: medium devsel

Only for my Intel newtork card whole .probe routine went well.

PCIC(4) 						   BSD Kernel Interfaces Manual 						   PCIC(4)

NAME

     pcic -- PC Card bridge driver

SYNOPSIS

     device pcic
     device pccard

DESCRIPTION

     The pcic driver provides support for older ISA and non-Yenta PCI PC Card bridges.	The pcic driver supports most ExCA devices attached to the
     ISA bus or PCI devices that do not conform to the Yenta specification.

     The following ISA devices, or true clones, are supported in the current code.

     Intel i82365SL Step A
     Intel i82365SL Step B
     Intel i82365SL Step C  Intel's original 16-bit PC Card controller.
     Intel i82365SL-DF	    Intel's last version of this device.  3.3V support was added.
     VLSI 82C146	    An older VLSI part with some issues on some machines.
     Cirrus Logic PD-6710
     Cirrus Logic PD-6720
     Cirrus Logic PD-6722   Cirrus Logic's pcic controller.  Compatible with the i82365SL Step C with the addition of a different 3.3V control.
     Ricoh RF5C296
     Ricoh RF5C396	    Ricoh's PC Card bridge chips.  These are compatible with the i82365SL Step C, but with yet another different 3.3V con-
			    trol.
     Vadem 365
     Vadem 465		    Compatible with i82365SL Step C.
     Vadem 468
     Vadem 469		    Like the earlier Vadem models, but with Vadem's own, incompatible, 3.3V control system.
     IBM PCIC		    IBM clone of the original i82365SL part, with its own ID register value.  Has no 3.3V ability.

     Many other vendors made parts in this arena, but most of them were compatible with one of the above chipsets.

     The following PCI pcmcia bridges are supported:

     Cirrus Logic PD6729
     Cirrus Logic PD6730

     O2micro OZ6729
     O2micro OZ6730
