memtest from F17 beta DVD images

[Przemek Klosowski]

I booted the F17 beta ISO (x86_64, if it matters) on two laptops and 
tried the provided memtest. In both cases it reported insane amounts of 
errors in test 7 after running successfully through tests 1..6. The 
reported error addresses are in the 120 MB area.

I checked that when memtest is configured to go directly to test 7 the 
errors appear right away.

I have not had the chance to retest with older images but the chance 
that both laptops independently developed RAM problems in the same area 
seems small. I'll do more tests and file a Bugzilla report if it checks out.
