I had a similar issue with the 8G (class 4) card I got for my phone. No matter 
what I did, it wouldn't work in the SD slot. Other cards did, but not that 
one.

Eventually I just stuck it in a multi-card expansion unit that plugs into USB 
and it worked just fine. I suspect issues with the card itself - possibly 
timing related and this confuses the controller. But I never proved this one 
way or another.

Maybe you can try a similar USB unit? They are dirt cheap.

My on-board SD controller for comparison:

Adapter (rev 22)
