In general, it's best to leave Speculative Processing (SP) off.  I believe
that the last PCI PowerMacs (basically, the 8600/9600 Mach 5 systems) have
firmware which allows SP to be safely turned on; but all earlier PowerMacs
do not.

The performance benefit from SP varies, but is generally not very large
(at best, a few percent).  The downside is that errors caused by enabling
SP on machines not designed for it can be intermittent and catastrophic
(won't boot, corrupted data, etc).
