The problem is more widespread than just Power PC. The same failures (+/-29) are also seen on the three s390x buildbots. There are multiple failures of testExactPowers(Negatives) on
http://buildbot.python.org/all/builders/x86%20Tiger%203.x/builds/11140/steps/test/logs/stdio
The first is
AssertionError: 9.000000000000002 != 9
An slightly different failure happens on AMD64 Free BSD and Open Indiana buildbots:
http://buildbot.python.org/all/builders/AMD64%20OpenIndiana%203.x/builds/11077/steps/test/logs/stdio
