Stop this. You can bypass cache on lots of chips. Most caching cpu's
can have cache bypassed in the page tables. A second way, if your board
is designed to do it, is a software toggle of some sort. I think, most
modern cpu's, have a cache enable/disable pin.

And finally, you do not want to use pfld's that might access memory
that is in a cachable address range. (Right Larry?).
