That also includes the TrackIR, thanks to these guys and their Linux-Track project - which is still a bit rough in places but generally works fine with a variety of hardware (from webcams to TrackIRs).
In addition to the Linux-track stuff you'll also want the Linux-Track WINE plugin which presents Windoof apps with a TrackIR-compatible API. That thing was a pain to get running, and you might want to check out this patch by me to make it work properly with recent Linux-Track revisions.
Apart from those: no real problems after some initial conf.ini tinkering; no more inexplicable stuttering under Windoof, no more dualbooting and smooth performance with graphics options close to the top levels.
