    Subject[PATCH] CS89x0 demands too many pages
    The CS89x0 driver wants a 16KB or 64KB dma_buff (if use_dma and
    ANY_ISA_DMA), thinks it's asking __get_dma_pages() for 4 or 16
    pages, but actually it's demanding order 4 or order 16 buffer.
    Patch below against 2.4.2-ac9 or 2.4.2, offset against 2.4.[01].
