Is it worth detecting this and allocating 2 or 3 pages as required?

The OpRegion is always 8096 bytes? (two pages, but not necessarily
aligned)?

Do we need to worry about what is in the "slop" at either end of a 3
page region containing this? If they are sensitive registers then we may
have a problem.

Ian.
