I knew the solution would be something simple, more than likely related to my inability to read properly :D Thanks for the pointers Jonathan, sorry it took a while for the point to stick.
I guess the next natural question is, can I put my hardware to use helping develop support for this? I'm no programmer, but I can be a test subject for others working on this. And is it worth installing -current and sending the developers the dmesg for reference? I've just realised I've only ever been running -stable on this box.
