Well, Dave, you are going to have to explain to us how
this bursts the Acorn folks' bubble.  They have produced
a high-performance RISC processor which supports the
rounding modes that everybody's been talking about.  He
(Roger) didn't make any claims other than that, and the
fact that us 'mericans do not import ARM's.  ATT, on the
other hand, has an FP accelerator which supports these
rounding modes, but it is only used in a processor whose
machine language doesn't support them - the exact problem
everybody's been complaining about!  Some bubble-burster
you are... :-)
