[Grml-devel] Elantech Touchpad Bug in Kernel 3.1

[Brad Cable]

Hello,

There is a bug with the Elantech touchpad driver in linux 3.1 that has 
been fixed in 3.2, but it sounds like 3.2 is going to be released too 
late to make it into grml.  I have tracked down the exact patches that 
get this working, compiled 3.1.5 against those patches, and I'm 
currently running it with the driver working correctly.

I was told that I can request for certain patches to be applied to the 
kernel for stable grml, so here is the list of patches that gets this 
working.  This adds support for a ton of new hardware touchpads.

If you check here:

https://github.com/torvalds/linux/commits/master/drivers/input/mouse

The last 14 commits make this work.  The MacBook commit appears to have 
been applied to 3.1.5 already, so really it's only the 13 there that 
support the newer hardware.

As I said, I'm currently running this kernel so if there is anything you 
want me to test or if you have stability concerns, I can test whatever 
on this kernel pretty easily.

Here are the hashes of the commits I patched against:
