Well, I got it working well enough (the old one) on a ppc405 about 5 or 6 years ago... It did require some endian & dma mapping fixing, iirc, in the hisax pci driver, but nothing very tricky. What bugs me is that we -fixed- at least some of these things in the old stack, up to the point where I could use it reliably in some commercial products, and now we are merging a new stack which, in that area, is a clear regression over the old code. One basic premise to me for replacing a whole stack with a new one is that the new one should be -at-least- as good as the old one in all areas, and those (virt_to_bus and endianness) are pretty major.
