+         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 assistance 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.
