The atombios messages are due to bug 67043. You can revert the patch referenced in that bug to fix that. danvet supposed has a v2 of that patch which doesn't break resume.
Also, does it work any better if you drop all the pm-suspend quirks? You shouldn't need them for KMS.
ok, so reverting the original patch and applying the attached one is the correct order ? or shall it be applied to current source ? - (probably the former) - will try
I hesitantly will give it a try without the quirks - up until now the box always would hardlock without those quirks - both on xf86-video-ati or fglrx
but ... it might work already without quirks since via Xfce it suspended and resumed successfully to ram 2-3 times already from the panel menu with non(new)-DPM so far
thanks !
