I can also reproduce the S3 issue on my hardware.
It can sleep to memory (S3) but can't resume after pressing power button.
It's not a recent regression. It exists for a long time.
We filed a bug for Dom0 S3 more than 1.5 years ago.
http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1707
(There are some comments in this bug.)
There are 2 reasons why we didn't list this bug in our recent report.
1. our report is based on our automatic testing, but dom0 S3 is not included.
  It's difficult to make such a case automatic.
2. We really missed the bug in our recent reports. Sorry.
  We'll add it in the old issue list for tracking.
