Then you should probably ask the vendor's support folks.

In the source code. You received the source code or at least a
written offer for it with your board, didn't you?

OK.

I guess it's OK. I don't know your hardware, but most probably both
chips are operated as 2 x 16 bit in parallel to form a single 32 bit
wide bank.

Unfortunately they never bothered to submit their code back to the
public source tree. All I know is that Detlef Vollmann once (August
2005) mentioned that there is some port, but he never submitted a
patch either.
