Bug#946118: synaptics touchpad does not work in debian installer graphical mode

[Samuel Thibault <sthibault@debian.org>]

Hello,

Thinking of it... IIRC the touchpad is not working on my DELL XPS13
laptop in g-i. What I can see of it on normal boot of installed system is:

[    6.097298] input: DELL07E6:00 06CB:76AF Mouse as /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-8/i2c-DELL07E6:00/0018:06CB:76AF.0002/input/input12

and lsmod | grep i2c gives

i2c_designware_platform    16384  0
i2c_designware_core    20480  1 i2c_designware_platform
i2c_i801               32768  0
i2c_hid                28672  0
hid                   126976  4 i2c_hid,usbhid,hid_multitouch,hid_generic

I don't see the i2c_designware* modules in the g-i image, perhaps that
needs to be included for some hardware?
