You mean the old Savage DRM driver 1.0? That one didn't use DMA, which is about the same as setting DmaMode to "None" now. Another thing you can try is running textured applications with only AGP textures (with BusType "AGP" and DmaType "PCI"). Run the application like this: texture_heaps=2 <textured DRI application> This will disable the local memory texture heap and use only the AGP heap. If our theory is correct, it should lock up after resume.
