I tried all the ones listed in various combinations:

[root localhost ~]# pm-suspend --help
pm-action [options]

Options can change how the supend or hibernate is done.

Possible actions are:

  --quirk-dpms-on
  --quirk-dpms-suspend
  --quirk-radeon-off
  --quirk-s3-bios
  --quirk-s3-mode
  --quirk-vbe-post
  --quirk-vbemode-restore
  --quirk-vbestate-restore
  --quirk-vga-mode3

However they all seem related to kicking the gfx back into gear while my
issue is about the harddisk not activating again. Nevertheless I tried
them and it did not make a difference.

Same here :(

I think we need more than luck. Hopefully the regression will get fixed
soon.

That would not be a bad idea. Perhaps bugzilla an RFE?

Thank you for you suggestions.
