My suggestion would be to write a simple driver and communicate with it. That will free you from the availability of the CHUD API.

The problem with this is that the only thing I can visualize will work only on x86 (io port access). I can't seem to figure out a way to get "random access" to the PCI bus. Eg, I don't see a way specify a bus/slot/function and access its PCI config space, even in the kernel.

FWIW, I wrote a trivial kernel extension to allow in/out{b,w,l}, and our tools are working fine on Intel. Powerpc is still a problem, but since ppc seems to be pretty much dead, I guess I'll have to not worry about it. I would still be interested to know if it is possible somehow to access PCI device classes on a bus/slot/function bases so I could use the iokit IOPCIDevice::configRead functions..
