SATA controller not recognized in FBSD 7.1

[Elliot Finley]

I've got two of these:

SUPERMICRO AOC-SAT2-MV8 64-bit PCI-X133MHz SATA Controller Card

http://www.newegg.com/Product/Product.aspx?Item=N82E16815121009

each with 8 1T Hitachi drives hanging off them.  When booting, I see all 
the drives scanned and recognized by the controller, but I don't see 
them in dmesg or /dev.

I'm using FreeBSD 7.1-R amd64.  Is there a special driver I need to load 
to get FreeBSD to recognize these?

TIA
Elliot

P.S. I bought these thinking they would work because of this 
http://www.nabble.com/ZFS-Advice-td18842170.html thread and others that 
seemed to indicate people were using these with FreeBSD.
