Neither sparc64 nor sun4u has support for bounce buffers; it's not really worth the effort to implement IOMMU-bypass and bounce buffers for the few devices only doing < 32-bit DMA and for >= 32-bit DMA the IOMMU takes care of the address translation for all practical purposes. In any case this isn't specific to psycho(4).
