After I posted the test program to the 386 mailing list I got a note
from Intel saying that the test had to be performed over a range of
temperatures and frequencies. If your chip fails the test it's bad, but
if it "passes" it is not known to be good. Most chips pass under normal
conditions, then fail when (something) changes.

Since there is no way to change clock and temperature via software, this
"test" is only slightly better than nothing, maybe worse if it gives a
false assurance. I won't post it again because it's known not to be
reliable. If someone else does then blame them for the results.
