Sean, you appear to be saying that by removing block devices from FreeBSD, it is no longer possible to do direct, un-cached (i.e. raw) accesses. How is this the case? My understanding is that un-cached accesses are done through character devices, which is what we're keeping, rather than chucking. If I'm paraphrasing correctly, and what you say is true, then I strongly disagree with removing the block devices, though it seems unlikely that I'm understanding this correctly.
