Hi,
I'm not sure if this shall work, but do tryThe duplicate SLAB_xxx flags are now removed from the mainline. Use the GFP it again after installing the 'lirc*', i guess more specifically lirc-modules, but be on the safer side..
My friend wanted to get his tablet-pc touchscreen working... will WACOM do the job??

Let me know if it works..
