2.6.24 for x86, and 2.6.27 for powerpc. Sorry, this is a bogus report:

I tried to isolate the scattergather implementation, thereby the dev
pointer got NULL, which results in different dma_ops.

I am bringing a freshly written driver upstream 'altpciechdma' for the
Altera FPGA PCI Express Chaining DMA reference design. Will probably
appear in staging RSN.

Thanks for the help,
