I have a Silverstone case with an imon VFD and remote which works (apart from the pad) in 7.10.
With 8.04 the remote works the same but the VFD doesn't.
/dev/lcd0 is present and the LCDd.conf files match.
Current LCDrpoc version is 0.82.
ls usb reports the controller in both and ps reports LCDd and lircd in both.
THe /etc/modprobe.d/options file needs the following line added:
options lirc islcd=0
Or, if you have the iMon Pad as well:
options lirc pad2keys_active=1 islcd=0
