I assume the Fastlane's driver is smart enough to allocate its own memory first for DMA, and not to try to DMA to other kinds of memory that it can't, but it still might be smart to set the Mask to omit your CPU card's local memory if it has any, as well as any memory on the motherboard. i.e. just Z3 memory expansion space. Obviously you can't guarantee where the card's memory will appear (due to autoconfig) but at least you know it will appear in that range.
