On some Thinkpads, the extra buttons are used for the trackpoint, so they should be reported as "main" buttons, not extended ones. An (undocumented) information query was added to the firmware to report when this is the case, however it is not advertised as supported by the firmware itself by the usual mechanism. What we do is (just as the Linux driver) detect that the tocuhpad has a PS/2 passthrough (likely used to daisy-chain a trackpoint on the same PS/2 port) and also advertises extra buttons (an unlikely case, it is already uncommon to even get a middle button these days...) and assume that the information query is available then. When the query is available and reports the quirk, the extended buttons are reported as 0, 1, 2 (left, right, middle), instead of extra buttons the userland would have no idea what to do with.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!

Contributing documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
