    Are you sure you want bit 5 clear (EPP+ECP disabled according to the manual)?
    The code in drivers/parport/parport_pc.c reads:

            /* if ECP not enabled, DMA is not enabled, assumed bogus 'dma' value */
            if (!have_eppecp)
                    dma = PARPORT_DMA_NONE;

    It looks like it wants this bit set...

    I would really appreciate a comment from jgarzik on this matter:
