You can still get it from our BerliOS SVN repository (soon we will switch to github): http://developer.berlios.de/svn/?group_id=6475 In the README is described how to build the relevant kernel modules. Be aware that for that old version only the old SysFS interface is available to setup the bit-timing parameters (bitrate, etc.).
