Yes, this is strange, how could the version be wrong?... I'm running
-rt22 (and previous versions) on a lenovo t61 and resume works fine. 

It would seem that it is suspend that is triggering the problem. Maybe
that would explain why it boots instead of resuming, it did not really
suspend. 

What mix of packages do you have installed with rt16, and what with
rt21?

  rpm -q -a | grep rt21
  rpm -q -a | grep rt16
