Intel ICH7R RAID controller working on 6.1/STABLE?

[H. Wade Minter]

I'm considering ordering some of these servers to run FreeBSD 6.1 or 
6-STABLE on, but they have Intel ICH7R RAID controllers on them.  Googling 
around, I'm seeing conflicting information as to whether or they work, or 
work well enough to use in production.

The server specs are here:

Can anyone confirm or deny its support under FreeBSD?

Thanks,
Wade
