How can I fake a device ?

[Iasen Kostov]

    Hi,
I want to know is there a way to call *_probe (for device driver) with 
fake (PCI) device that does not exists in the system ?
First of all a cant find how "struct device" is declared (i've searched 
even the compile/ dir) and second I think that I'll need to intercept 
pci_get_vendor and pci_get_device funcs with my own which should detect 
the fake device and thus will return vandor/device that I need to fake. 
I realy don't need anything else except _probe ...

    regards.
