Did I say those were the only ones?

	(3) No support for ATAPI (show-stopper).

	(4) Some missing target drivers (show-stopper).

	(5) Serious lack of documentation (show-stopper, because without
	    this, how do we make the plethora of HBA drivers we support

	(6) There seems to be this notion of "physical addresses" within
	    the CAM code itself.  What's going on here?  This isn't
	    exactly portable.

	(7) Host bus adapter drivers misuse bus_dma, almost as a feature.

Anyhow, those are a few more based on my very quick glance at FreeBSD-current.
