Hi,

I have a TimelineX notebook and the touchpad only works as normal ps2/mouse,
after adding the following to the model_data the touchpad is correctly 
detected by
the system as ALPS device...

     { { 0x73, 0x02, 0x64 },    0xf8, 0xf8,
         0 },              /* Acer Aspire TimelineX */

Now the device is also detected by Xorg as alps mouse. Scrolling and 
double tap
etc. doesn't work, although that may be a case of picnic, although I'm 
not sure,
since gsynaptics shows the scroll as enabled.

The E6/E7 detection report from debug enabled alps.c

Feb  5 14:07:00 freshlulz kernel: alps.c: E7 report: 73 02 64

The DSDT file is attached. The relevant section of the dsdt

                 Device (PS2M)
                 {
                     Name (_HID, EisaId ("SYN1B22"))
                     Name (_CID, Package (0x03)
                     {
                         EisaId ("SYN1B00"),
                         EisaId ("SYN0002"),
                         EisaId ("PNP0F13")
                     })
                     Name (_CRS, ResourceTemplate ()
                     {
                         IRQ (Edge, ActiveHigh, Exclusive, )
                             {12}
                     })
                 }
