nope, it works just fine, it's even listed in the amr manpage.

That's a controller issue primarily, although you will have to expand the 
freebsd slice, which might require some magicks, or a backup/restore.

there is an open source monitoring tool ( not management ).
The card is fully bios manageble.

I'd purchase the 300-8x, which should have a substantially
faster onboard cpu. The 150-x is a bit of a dog compared to
other current sata raid options.

most of these questions arent freebsd specific, and quite offtopic
for current@ list ....
