LIRC

судя по анонсу, в Knopp Myth есть код для автодетекта некоторых ИК ДУ:

KnoppMyth R5A22 by Cecil - Wed, Oct 19th 2005 23:09 PDT About: KnoppMyth is an attempt to make the installation of GNU/Linux and MythTV as trivial as possible. It includes everything needed to get your set-top box up and running in as little time as possible. Changes: KRP logic was integrated into the installation and configuration scripts. Dragon installation and configuration is now 99% automated. System independent auto-detection and configuration was implemented, and more LIRC remotes are detected and configured. Channel icons now download automatically. nVidia drivers now auto-install on first boot. Key bindings were unified across applications. An ATI Remote Wonder button repeat bug was fixed. MythWeb now uses basic Apache authentication by default, and links to media work again. IvyTV 0.4.0 support for BBTI/Technisat AirStar-HD5000 was added.
