This fixes some problems with ATAPI devices on nForce4 controllers in ADMA
mode on systems with memory located above 4GB. We need to delay setting the
64-bit DMA mask until the PRD table and padding buffer are allocated so that
they don't get allocated above 4GB and break legacy mode (which is needed for
ATAPI devices). Also, explicitly set a 32-bit DMA mask before allocating the
legacy buffers since setting the DMA mask affects both ports and we need to
ensure the second port's buffers are allocated properly (fixes a problem
with the previous version of this patch).

Would this be worth sending to stable team for 2.6.22 & 2.6.23 ?
Likely (after it gets merged), those versions would have the same bug..
