Yes, you can flash newer firmware on, it is a separate chip with a separate EEPROM, no relation to the system BIOS.
It won't gain you anything, though. Later firmwares behave the same in every way I have been able to check. If your controller is taking a long time to boot the disks, you have a duff component somewhere (cable, disk, controller).
