If you boot your machine with Virtual, checking that the About the Finder
box shows that you have 8,192K of RAM DOES NOT mean that Virtual OR your
PMMU are working properly.  All that shows is that Virtual has TOLD the
Macintosh that it has access to 8 megs, and the Mac believed it.  The
paging would still fail if your PMMU were not working properly.

The only way to check your PMMU with Virtual is to boot up, and then load
several memory-intensive programs into memory and use them.  Load your
favorite GIF viewer and look at a few full-screen images.  Try Canvas on
a large document.  Basically, until you've convinced Virtual to do some
page swapping, you can't be sure the PMMU is actually working.
