The ralink drivers from their website don't compile against current Ubuntu kernels. I've prepared some patches for a friend (I don't actually have this hardware myself, so I haven't really tested this!). You can find them below; they can be re-distributed freely.
Please be aware that I know nothing about wireless hardware, so anything may go wrong when you use this code. I cannot give any guarantees.
Here's a patch if you want to compile their driver against the Natty kernel 2.6.38:
