I have the same board with the same kernel. For some reason the card reports 32mb with lspci. I read once that this might have to do with having the frame buffer console enabled (seems doubtful). In any case, the card only has a 16mb frame buffer ; enabling a 16mb write combining range starting at the prefetchable buffer start address is sufficient, enabling 32mb will yield no improvement. And enabling write-combining on the non-prefetchable range will have disastrous results.
