I dunno.  i860s will work with denormalized numbers (which kills
performance, IMHO).

Not really, talk to Boeing, for example.  I wish they'd publish on what they're
doing, but they're so damn secure that some of their employees almost
had a fit during an Intel class when it was mentioned that they
had a ipsc/860 and were running LOOCS.
