Quick note about the elantech driver

Quick note about the elantech driver

[Éric Piel]

Hello,

I've just found out that there is a patch written by Elantech themselves 
for getting more versions of their touchpads working with the latest 
kernels:
https://launchpadlibrarian.net/71387234/01elantech_2.6.38.patch

So if anyone has problem with a new elantech touchpad she/he can try 
this patch :-)

I'll try to have a look at it and see how to put the same functionality 
in a more elegant (and acceptable) way. But for now I have only very 
little free time, so it might take time. If anyone was beating me at it, 
it would be with pleasure ;-)

See you,
Eric

PS: In case someone is interested, I've also noticed the source of some 
kind of X driver there: 
http://people.freedesktop.org/~whot/patches/etd7-ps2-drv_1.4-1Free1.tar.gz

I've tested this on 2.6.39.1 (applies cleanly) with ASUS K53E and it
works.
On the module load I get this:

Multitouch now works.
