It doesnt work with SMP last time I enquired. Otherwise yes, it would
be sensible to put it in as an option(it needs to be an option as some
boards even pentium ones are slower using it).

It will be slower on any Pentium with a 32-bit external memory bus
(some laptops are like that). For that matter, it's faster even on
some Pentium Pros.
