Just doing the same as Linux does with respect to memory caches.

I have seen hundreds of reports of corrupted systems,
which are traceable to bad SIMMs or marginal chipset/memory
timings in a system.

Yet, for some inexplicable reason, Linux continues to default
to "external cache == ON" on all systems, when it would be a
heck of a lot better off to disable caches at boot time.

After all, a user-level utility could easily be written (with
kernel hooks) to turn the caches on after booting, if safe to do so.
