Thanks for mentioning this.  I'm running it right now on my 8500.  It
seems to work fine, although it was only able to mlock 50 MB of the 96
MB I have installed.  But it clearly provides a much more exhaustive
test than the Newer Technologies RAMGauge.

I could probably get it to test more memory if I had less running on my
box, I'll try running it from single-user mode (give the -s kernel param
to BootX)... no, if I boot single-user I can still only test 50 MB.

Maybe I could compile a minimal kernel that would load this off a
ramdisk image, and use memtester for "init".

Even better would be to implement memtester as a device driver and load
the whole thing in the kernel.
