The LED behavior may relate to the backplane, the controller and the disk. What chassis/backplane are you using?
If I remember correctly, on most Intel backplanes when you use SATA drives the drive LED remains off, while with SAS drives the LED is on upon drive presence.
Also, your BIOS and driver version seems really old, although the BIOS string you provided is not complete and I can't tell exactly which version it is. Check http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=2487 for updated BIOS/FW/driver.
