While you wrote your mail, I got S3 working here, but your suspend script is very appreciated. >>Oh, and once I get S3 working with 2.6.9 I'll do a binary search >>to find the changeset that is causing the problems after 2.6.9 >>and report back. > > That would be most appreciated. I still haven't fully recovered from > trying 30+ kernels / configurations to find the borked patch ;) A first hint: CONFIG_REGPARM killed swsusp in some kernels before 2.6.10-rc3, it could also be the culprit for S3. Besides that, I think we could convince the X.Org developers that the "get display working" bug is their problem ;-) It seems they have merged some suspend/resume bugfixes for Radeon and will merge at least one more bugfix in the next few days. Basically, it should be possible that the normal Radeon Xserver rePOSTs the card itself once it detects a resume event. If that is done properly, we could get rid of the hack completely and would only have to live with the text console. Once these patches are merged completely, I'll try a current X.Org build and open a bug with X.Org if the situation isn't better.
