Yes, but the vendor screwed it up (probably to save money). This is _very_ common. It is very unusual to have a multifunction I/O card that gets this right (in fact Lava is the only one I can think of off-hand).

If we have to do this, then Gunther's approach (multifunc_quirks or whatever) looks a lot better than having a separate driver for every single multi-IO card.
