During the suspend/resume programming I came to an issue that first 4KB of
memory must be clear with 0s because otherwise the resources of K8 will be
totally messed up.

res = probe_resource(dev, 0x100 + (reg | link));

This is called with dev = NULL and this is no good for probe_resource at all.
The attached patch fixes the potential problems and of course the problem
itself. On one particular place was missing test if the device really exists.
This was copied to fam10 and perhaps the same issue is in v3 (DID NOT check).
The rest of the patch is just very paranoid and do all checkings.
