[BA] Fixed 3ware issue with new controllers. Documentation said

       that one could address up to 24 disks on a single controller,
       but in fact one was limited to 16 disks.  This is now fixed:
       up to 32 disks can be addressed.  Thanks to Adam Radford.

       NOTE1: I have patched the Linux and FreeBSD code but not
       modified the Win32 code. Christian, please remove this
       note if no modification is needed.

       NOTE2: NOT TESTED ON LINUX.  Do not use this on a production box!
       I will remove this NOTE2 as soon as some positive test
       reports are recieved.

       NOTE3: NOT TESTED ON FREEBSD. Do not use this on a production box!
       I will remove this NOTE3 as soon as some positive test
       reports are recieved.
