The iosniffer driver appears to cause an immediate reboot (triple fault?) on installing its hooks. Given the low-level nature of the crash, the thought of tracking it down makes me shudder. If anyone else wants to try installing the driver, it would be nice to have a second opinion. I guess it's back to the virtualization approach.
