Power Management 1 FAIL : Required kernel configuration for

I am little confused with the way above results are published. Not able
to make out whether they are failing or passing.
2) uname -a
Linux 2.6.27-gcov-autokern1 #1 SMP Wed Oct 22 19:26:13 PDT 2008 i686

I have built the kernel with all the options mentioned in your README.
