+	  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.
