HI Roger, The files work just fine under Kubuntu 7.10 with the Gefore 6200 + NVidia drivers machine I'm working on right now.
This looks to be a hardware/driver bug. I guess you could try avoiding compressed imagery, instead opting for downsizing the imagery to get the memory footprint down, a bit of hack but for lowly hardware it just what you might have to do.
