Got it to compile

Had to delete the lines in the link you posted as well as 
Line 34
#include <linux/config.h>
&
Line 43
#include <linux/devfs_fs_kernel.h>

And then modprobe imon_vfd but still no /dev/lcd* devices I get info in messages, I even tried rmmod lirc_imon & lirc_dev before loading imon_vfd but still no joy

I'll try posting on Venky's forums

Thanks for your help everyone
