Yes, and in today's world, it is likely to be some young sub-saharan african pup who can't just go down to the local retailer and drop $400 on a new system if his won't install...

Years ago on the CD distributions there was a file in the root of the distro labeled "hints" or some such. It was also on the website. It contained all the little workarounds for SPECIFIC pieces of hardware. I know as I wrote several entries for it. That apic problem was listed in there as were several others, I know some for laptops specifically. Sometime during the FreeBSD 4.X series one of the developers got a bug up their ass that somehow this was the wrong place for problems to be listed. Something along the lines of these problems aren't FreeBSD problems they are sucky hardware problems and it makes FreeBSD look bad to have the workarounds even listed at all, and we have the bug database and these icky ugly things really ought to go into the bug database. So this file disappeared. As did every other easily recognizable place for submitting hints. As did the specific e-mail address for hints to go to. These installation problems IMHO PROPERLY belong in the README for the distribution. That is the FIRST place that someone BRAND NEW to FreeBSD is going to look for them. No FreeBSD newbie who has oddball hardware that has bugs in it, is going to take the time spending hours reading the Handbook or searching the questions mailing list archives for tidbits, or querying the bug database for PR's for their gear. Any newbie to FreeBSD is going to do the same thing that they do to any other OS, they are going to stick the CD in their oddball hardware and boot it, and if it doesen't come up they will look at the README file that came with the ISO image they downloaded, and if the hardware-specific workarounds for their machine aren't there, they will discard the ISO cd and move on to some other Open Source OS. For all the huffing-and-puffing on peer-review for the Handbook, well that is fine for that. But an install hints file's very usefulness is junk if a committee is reviewing it. Hardware-specific install hints are, by their very nature, NOT guarenteed to work. They may even make things worse. All they are is user-developed workarounds that may or may not be The FreeBSD Way of doing things. The only thing that can be said about them is that at one time, one year, with one particular piece of gear, someone tried some off-the-wall thing and it worked. It might not ever work again in any future version of FreeBSD. There might be manufacture-specific BIOS updates that fix things. There might be a driver update in a later FreeBSD version that fixed that specific thing. But, it is a last-ditch suggestion to try when the 'normal' way of installing something doesen't work. I don't see much support for recreating the install hints file, so I really feel little incentive to contribute workarounds at this point, even though I have a whole collection of them for the specific systems I've installed FreeBSD on over the years. Submitting them to the PR database is worse then useless, because they invariably involve 2-3 year old hardware (or older) and the developers have ZERO incentive to work on them. So the PR's just get stale and then do-gooders come along 2-3 years later asking the original poster to verify if the problem still exists in current FreeBSD, and when the OP says how the hell do I know, they get closed. Sure, it might look strange to have a hint about installing on an old HP Netserver to make an EISA change, in this day and age, in an install hints file. But, goddammit, where the hell else are you going to see that? And you just know that somewhere, there's some young pup that has dragged one of those out of a Dumpster somewhere and is going to try loading FreeBSD on it.
