Except if you don't load ohci1394 or load ohci1394 with the parameter phys_dma=0. Switching physical DMA off will work fine with raw1394, dv1394, video1394... It will just break sbp2 until I get http://bugzilla.kernel.org/show_bug.cgi?id=6393 fixed. (It's not high on my list, and it is a nuisance to implement in an platform independent way.) I don't know if eth1394 works without physical DMA..
