    Subject[PATCH 2.6.17-rc5-mm2 17/18] sbp2: provide helptext for CONFIG_IEEE1394_SBP2_PHYS_DMA and mark it experimental
    It appears I will not get it fixed overnight.

    + This builds sbp2 for use with non-OHCI host adapters which do not
    + support physical DMA or for when ohci1394 is run with phys_dma=0.
    + Physical DMA is data movement without assistence of the drivers'
    + interrupt handlers. This option includes the interrupt handlers
    + that are required in absence of this hardware feature.
    + This option is buggy and currently broken on some architectures.
    + If unsure, say N.
