Does anybody have any info on this?  Please respond by mail.
I know you can spot a 386 in real mode by trying to set the IOPL bits in
the flag word, but this doesn't work in virtual 8086 mode.

In general, any test should not involve triggering a trap.  There
are obviously lots of tests to try that would trap on one machine and
not on the other.
