What Fibre Channel cards work in the Mac Pro 7,1?

The old LSI cards are not showing up in the Expansion slot utility.

Do they need to be in a specific slot? Any love here?

You used to have to use the Apple fiber channel Utility to configure the card.

I am not sure whether that is still true -- the one I found says it works in 10.4

You know those Two Ethernet ports at the base of the chassis can do up to 10G Ethernet over copper, right?

Two 10G Ethernet copper plugs are nice, unless you need to connect to Fibre Channel switch. Unfortunately the old apple (LSI branded PCI Express cards) are not appearing in my system profiler or expansion card utility. Not sure what's up with that.

An Apple SE told me "The reason the card might not work is that some older PCI cards might use 32-bit Option ROMs that aren't compatible with the new Mac Pro 7,1. If you install a PCI card that uses 32-bit option ROMs, your Mac Pro might not start up correctly." I am not convinced on that one, because the machine starts up fine. But they may have a point about older cards. I need to know which cards are effected though.
