I have 1.17 installed at the moment. It looks like 1.21 is current, so
I could try updating it. But the Fedora 15 2.6.38 kernel worked fine
with this controller and cards, so I don't think BIOS version is an
issue. Also, there's nothing obviously related to the SD controller in
the release notes (not that I trust their competeness).
