Device probing

I am trying to port the Linux i810 DRI kernel module to FreeBSD and am having 
some difficulty recognising that the device is present in the system.  As I 
understand it, the list of unattached devices is passed to the probe method 
of a PCI kernel module so that the module can decide whether it is one that 
it supports.

Is it possible to attach to an already attached device?  The reason that I ask 
this is that a test module which looks for my i815 graphics card is able to 
find it if the AGP kernel module is not loaded, but if the AGP module is 
already loaded it can't.

I have tried RTFMing, but I'm not sure that I'm even looking in the right 
place.  I am running on FreeBSD 4.8 on a Pentium 3.

Any assistance or advice will be most welcome.

Thanks in advance...Geoff
