I believe the IOBufferMemoryDescriptor has a pageable option. This may be a good solution for your problem. Also note that the kernel virtual address space is limited (3 GB on 10.3 and later, 1 GB on earlier systems). So, it's not a good idea to allocate too much memory in the kernel, even if it is pageable.
