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.
