Are you sure that Vista isn't just verifying memory during startup/driver load? Seems odd to periodically scan memory. In the recently released Windows Hypervisor specification, in section 13.2.2 (Local APIC Memory-mapped Accesses), it's dictated that the APIC can only be accessed through 6 instructions. They are all >= 5 byte instructions. When I first saw that, I figured they were also patching.
