There is already a flag for kmalloc() to try to ensure the memory is DMA'able. So the other thing that needs to be done is to maintain a guaranteed dma'able memory cache (tunable by kernel parameter or perhaps even sysctl)
I can do simple device drivers etc but deep kernel hacking is beyond me unfortunately.
