Personally I think that fearing the FreeBSD CAM implementation just
because it doesn't support 100% of the hardware NetBSD currently
supports is silly.  Even if some hardware is (possibly only temporarily)
"lost" because of the switch, I suspect the gain is still far more

Of course I'm coming at this from the point of view of a user who wants
100% reliability and error handling in the storage subsystem, and I
don't care if that means forcing me onto newer and more trustworthy

Perhaps there really is a way to support "broken" hardware with the old
drivers and still allow the rest of us to get newer reliable and more
flexible drivers on "good" hardware, though in the interests of
correctness and such, I really don't care.  PCs *suck* -- who cares if
you have to run 1.3.x or older on broken hardware????
