I am not sure how much virtioSCSI stuff would help. Also, the way dma ops
are done in dragonfly may vary with other bsd flavours (you will notice the
difference once you start working on the port). I would suggest you to go
over the dragonfly mailing list archive and mail related to  virtio, go
through the dragonfly handbook and the previous code.
