I'm using aac:

aac0: <Adaptec SCSI RAID 5400S> port 0x1000-0x10ff mem 0xec000000-0xec001fff irq 2 at device 9.0 on pci0
aac0: StrongARM SA110 233MHz, 64MB cache memory, required battery present
aac0: Kernel 3.0-0, Build 5217, S/N 8a1f1d
aac0: Supported Options=53f<SNAPSHOT,CLUSTERS,WCACHE,DATA64,HOSTTIME,RAID50,SOFTERR,SGMAP64>

and it does this.
