That probably will not be a lot of help - then way memtest86 does it is
to create a stand-alone memory test that doesn't use an OS to run under.
Instead it talks directly to the hardware. It does a much better memory
test then you could do under Linux. I am not sure you can do a good
memory test on a running multi-user OS. It would definitly have to be
run by root. It would also play havic with the rest of the programs
running on the machine!
