answering to myself... :)

WIN_WRITEDMA_EXT & WIN_READDMA_EXT cases are not defined in hw/ide.c
I have no idea where to start to write a patch for these... :(

Until these and the atapi_dma are set/defined, no dma should work IMHO.
And this seems not to be OS dependant.

Which means the linux figures I got were wrong ???
