I have here an Intel SRCS28X with LSI chipset. Write performace is very poor
- max. 5MB/s reported by bonnie. It's a RAID5 composed of 5* 250 GB SATA and
a spare. This is how it gets detected:

amr0 at pci3 dev 14 function 0: AMI RAID <Intel(R) RAID Controller SRCS28X>
amr0: interrupting at ioapic2 pin 0 (irq 11)
amr0: firmware 814B, BIOS H431, 128MB RAM
ld0 at amr0 unit 0: RAID 5, optimal
