Sorry for taking so much time to post my reply, I marked the mail as TODO but forgot about it. Since there are so many laptops with ATI card and working hibernate functionality out there (my T42 works fine too), I would conclude that it is an issue with this specific laptop. It seems to be broken in many ways (loading yenta_socket with default parameters hard locks the machine). I don't think a workaround for this specific machine would make a lot of sense, as it is a rare model (Gericom Blockbuster XL something) and only sold in Germany and Austria AFAIK. Please mark as WONTFIX if you desire.
