Closing. The issue is from the graphic card (Nvidia Riva TNT2) which doesn't support suspending. The upstream page [1] doesn't mention any specific issues for that card. Depending on those issues it may not be possible to enable suspending for that card at all. (I guess that "Won't fix" would be more appropiate but I can't use that status.)
