I've just tried the firmware. I can confirm it's working for Xbox 360 remote!
Two remarkable things to notice:
1) now the iRda is working in Openelec without having to use the autostart.sh hack
2) the iRda is not working for normal MCE Remote....at least, is not working on my Harmony Hub when set up as MCE SE and MCE Extender.
thanks for this beta bios!
