RE: [PATCH] 2.4.19-pre8 Fix for Intuos tablet in wacom.c

Hi Frederic.

Can you take a look at this?

I've looked at the code at
http://people.mandrakesoft.com/~flepied/projects/wacom/ and found that
there's a couple of lines missing in the kernel driver. It seems that a
smoothing algorithm is left out
in the kernel source. My patch just circumvents that.
