I think it's the usual hardware designers' attitude that any bugs in
the hardware can be worked around in software.  And they can, it's
just that to address the problems properly is going to take effort,
and no-one has yet had the time, energy and motivation to sit down and
do that (and do it in a way which is sufficiently clean and well
though out to be accepted into the Linux kernel).  Fortunately Apple
never did a 750-based SMP system. :)
