Proposal: Clean up the xorg graphics card/driver list and remove these ones that do no longer work.

My script does autodetect and autoconfigure *all* graphics cards/chips for which are drivers available in FreeBSD. It also works with multiple graphics cards, autodetecting whether they can work together or not (when drivers cannot coexist). The script is not yet ready for release, as autoconfiguring multi-head configurations (eg multi-monitor configurations either with multiple GPU outputs and/or multiple graphics cards) is still WIP. (If you are interested in this topic anyway, please either mail me directly or open a separate discussion thread.) However, the problem is that some drivers can no longer work because libxaa.so (and maybe other xorg libs, too) has been removed upstream 10 years ago already. See this for more info: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257417 This is the background of my proposal: - Test all graphics drivers on real hardware whether they are still functional in currently-supported FreeBSD releases - Remove all those drivers that can no longer work because xorg upstream dropped support. - Feed back to xorg upstrean so they can obsolete/remove these now useless drivers. I'd certainly be more motivated to do this if it is being sponsored, as I have already collected most (except for a few very rare and expensive AGP graphics cards) of the hardware in question. Because, 1. it needs some money to obtain these lacking (past high-end, mainly workstation usage) cards, and 2. it takes some time to walk through them and test every and each of these.
