Kevin, we tried out a Supermicro server which had ICH7R motherboard and RAID was recognized fine. FreeBSD recognized all the drives as stand alone plus the "ar0" onboard controller.

We're able to monitor it using atacontrol status ar0:

 atacontrol status ar0
ar0: ATA RAID1 status: READY
   0 ad4  ONLINE
   1 ad6  ONLINE

Controller info:

atapci0: <Intel ICH7 UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x30a0-0x30af at device 31.1 on pci0
atapci1: <Intel ICH7 SATA300 controller> port 0x30e8-0x30ef,0x30dc-0x30df,0x30e0-0x30e7,0x30d8-0x30db,0x30b0-0x30bf mem 0xe0000400-0xe00007ff irq 19 at device 31.2 on pci0
