Sound sane to me. Have you seen http://sourceforge.net/docman/display_doc.php?docid=23693&group_id=102048
AFAIK there is noone around with the knowledge of VIA 3D spec so miss and try is the only way.

Isn't it possible to check your conclusions by masking the annoying interrupt on PIC and enabling it, say, 10 times per second via dynamic timer? It's a huge hack but it will show the cause of the starvation (although I'm almost sure it's IRQ).
