Yes, but you don't want to, for instance, pull a disk that is mounted or anything like that. For the most part you can just pull the disk and then rescan the bus using camcontrol so FreeBSD can detect that the disk is gone. I've got what is basically a 6040 -- a Supermicro 370DE6 motherboard and a Supermicro SC860 case (I think the 6040 comes with a SC840 case) -- and it works fine with -stable.
