Hi Timo,

First of all, thanks for the excellent status update.

I'm afraid these patches wouldn't work for the touchpad use case. Currently, 
in order to apply quirks, I have to rely on the laptop/netbook id (which I can 
access through both udev and hal) and apply the quirk only for these specific 

Unfortunately I have to rely on the product name 
(/sys/class/dmi/id/product_name) of the laptop because touchpads don't expose 
enough information in the kernel.

If these patches break my quirks (by overriding what udev does), I think that 
maybe we should reconsider their inclusion as, without quirks, some touchpads 
will "feature" the infamous jumpy cursor problem. This would be detrimental to 
some OEM projects (mainly Dell and HP).

Of course I'm open to better solutions.

Note: upstream doesn't seem to want the quirks to live in the synaptics driver 
and I wouldn't know what to do in the kernel to reproduce my quirks.

Yes, all the packages in my PPA implement the following blueprint:

Note: I haven't had the chance to test the drivers yet.
