Even if the bug was fixed, it still would not be possible for a company to
implement "virtual" memory on a 286 for the simple reason that there is NO
way to insure that the customer who buys your software has a good version
of the CPU.  Most (All ?) the ATs shipped by IBM have a "bad" CPU - by
IBM's choice.
