Why all that when you can just do:

 os.path.isfile("/dev/tmp0")

??

IIRC, /sys will never be mounted inside the ramdisk by default.  So
the initial check is pointless.  Further, I think it would be better
to put /sys in the fstab of the ramdisk instead of having every test
mount it manually.  This makes the tests longer and is something that
probably needs to be on by default.  I can cook up a quick patch if
nobody else volunteers to do it ;)

Thanks Stefan!
