It's an AMD Mobility Radeon 4500 Series. It doesn't appear as though Dege tested dgVoodoo 2 on any DX10 AMD hardware (the oldest that he lists is an AMD HD 6450), so perhaps it has issues with that era of AMD hardware, at least on the mobile side (where I've found that AMD stops updating drivers after only a year or two). For the record, the ATI fix didn't help.
Anyways, it doesn't matter too much. I've already updated the few wiki pages to list DX10, instead.
