I really like this idea. I'm slightly worried that you'll end up with a pile of other bugs that just waste time though (not from Gentoo, but from other distros). About a month ago I tried to get a patch from Mandrivas's kernel. It was 2.6.12 with loaaaads of patches, so many that they revealed a very obscure bug in diffstat when trying to create these statistics: 2257 files changed, 363439 insertions(+), 22957 deletions(-) As well as those ~700 patches, they also include 38 tarballs of out-of-tree modules (mostly drivers), which they then build into the kernel RPM. So you might even get some bugs on things that aren't even in the kernel tree in those cases... But for Gentoo at least, I think both the Gentoo maintainers and the upstream developers would find it really useful.

I agree that there is an issue with getting the reporter to sign up for yet another bugzilla, but I don't think there would be any problem with mirroring: I don't see why we'd need to mirror anything back, except maybe the resolution of the bug. I need to give this more thought.

I'd love to see these merged. Michal can provide you with clearer answers but here is what I know: fbsplash was submitted about a year ago. Some developers commented "do it in userspace, you can do almost all of that there", and others gave feedback on things which must be changed or fixed before it is to be considered. I don't think Michal has had time to finish addressing those points -- when are you going to get SuSE to hire him? :) I don't think fbsplash is too far away from possible kernel inclusion, but vesafb-tng is. It is x86-only and is a big hack by design. Here's a recent comment from Michal:

So, did you show them the speakup patch? :) *runs for the hills* Daniel -- gentoo-kernel@g.o mailing list
