can't you get that information by using the combination of compat4x package, the amrcontrol tool from E Moore? (see http://people.freebsd.org/~emoore/MegaRAID_SCSI/). i've actually succeeded in rebuilding a RAID on a Dell PE2850 using the MEGAMGR application which provides the same GUI as the BIOS interface does. get the asci character set of your terminal right (search google) and you can manage. there seems to be no sourcecode available of the amrcontrol tool that allows a clean build unfortunately.

However, under heavy I/O load, the amr driver returns meaningful information. This is the reason why amrstat.c make a few attempts. Since this is only to send a mail for an alert, We ignore these "false positive". Pierre David
