There's work in progress to get the new 6gbps LSI HBAs and RAID controllers 
working in FreeBSD, but so far the driver is pretty experimental.  Currently 
there's nothing in the tree, but hopefully soon there will be something ready 
for testing.

As far as what you are seeing on boot, the system BIOS is seeing the 
controller and disks, but FreeBSD doesn't have a driver so once the OS is 
charge you get the no disks found message.
