Um, well if you are doing a consistent_alloc() then surely you are keeping the dma_handle around which is your physical address. If you want the kernel virtual address then you can apply __va to that. So, you have the cache inhibited mapping in vmalloc space returned to you, the physical address provided in dma_handle, and a kernel virtual address that can be trivially generated.
