More on non-recognized SATA hardware

I just noticed something today in the boot messages that I hadn't
noticed before: it appears that my SATA controller is being probed as a
RAID controller, but without any driver being attached.

Booting a CURRENT snapshot from 11/02, I'm seeing something like:

pci0: <mass storage, RAID> at PCI 9.0 (no driver attached)

Would it be a simple matter of patching one of the existing RAID
hardware drivers (ahci, perhaps?) to recognize my specific device?  And
if so, how can I go about doing this with no existing FreeBSD
installation?  Or, could somebody do this for me and create a mini-iso, just enough to get me started with a minimal base system?

For what it's worth, here's the relevant info from Ubuntu's lspci
command:

Please help!  I've got a serious FreeBSD jones going on here!  It's been about two months now since my last computer died and I've been without FreeBSD ever since.  Ubuntu is an OK temporary substitute, but I want my FreeBSD back!  :-)

Thanks!
