    Its a workable answer, but not the right one. The right one is to propogate
    the use of scatter gather better and eventually (2.3.x I hope) DMA to
    user pages. Modern SCSI controllers dont need 1Mbyte of linear memory
    for this. And non DMA old ones are generally sufficiently dumb you can
    implement scatter gather in the cpu driven byte copy routines
