would definitely be helpful (for a number of reasons that are
outside the scope of my question)...
I'm really only concerned with one or two processes
If you can make some minor changes to the application and write an I/
O kit driver, you could easily have the app issue an I/O against the
driver and then have the driver use the IOKit functionality to do the
virtual->physical mapping. That avoids trying to go backwards, which
is what you're describing there.
