There are only 3 options, and RAID+AHCI is the only option for AHCI.  
I can remember the wording for the other 2 options, but it is  
something like combined controller and separate controllers.

I am not sitting in front of the box, but here is the openbsd dmesg  
output if that helps. Openbsd did install (with the RAID+AHCI turned  
off) and is somewhat working.

bge0 at pci4 dev 0 function 0 "Broadcom BCM5752" rev 0x01, BCM5752 A1  
(0x6001): apic 1 int 17 (irq 5)bge0: firmware handshake timed out
, address 00:18:71:6b:ee:7c
