We emailed back and forth extensively about how this has not been true since early this year. Modern laptops are using libata for the ICH6M support, simply because libata claims that chipset, and the IDE driver does not. These laptops are using PATA drives (eg. "FUJITSU MHV2100AH"). > Exaggeration. We're talking about a single #define here, to enable ATAPI. Fine for ATAPI, though it's two defines -- need to also enable DMA. And Passthru is much bigger than a pair of #defines. If we want more testing/feedback on them, they've got to be put into wider use. That simply doesn't happen when they're tucked away in git repositories. Sure, *I* using them from your git, but there are tons of other people for whom that is an overly complex method, and the result is that few of us bother. On the other hand, some distros (eg. Ubuntu) are shipping with Passthru included in their kernels, because it's so necessary for things like laptop-mode. Push some of this stuff out to the -mm tree, and maybe we'll get more people exercising the code, and it'll progress more quickly. "Release early, release often" -- the open source mantra. Cheers!
