RFC: ATA to CAM integration patch

[Boris S.]

I'm using your 29-june patch (including the ALL_SLOTS_BUSY fix) since 
yesterday without any problems!

I use GUID partitioned gmirror and zfs on a AMD780G based mainboard.

The only irritating thing is that the zpool now shows gptid's instead of 
the partition names.

Boris
