So everyone who is interested knows, the PERC4ei is an amr(4)
controller.  The relevant bits from dmesg:

amr0: <LSILogic MegaRAID 1.51> mem
0xdfde0000-0xdfdfffff,0xd80f0000-0xd80fffff irq 46 at device 14.0 on
pci2
amr0: <LSILogic PERC 4e/Si> Firmware 516A, BIOS H418, 256MB RAM

amrd0: <LSILogic MegaRAID logical drive> on amr0
amrd0: 69880MB (143114240 sectors) RAID 1 (optimal)
