Oh man, I haven't laughed this hard in months, maybe years. I agree w/ 
your assessment, I was hoping someone might have a magic bullet to save 
the day, but I guess not. Is the memtest86+ source available ? If so, 
maybe someone else (*not* you or me) will pick it up. It was/is a nice 
facility when it works. As it happens, my ongoing Passmark memtest 
v6.0.0 got unstuck & has proceeded into the 2nd pass, so I may be OK 
there ....
