SubjectRe: ALPS touchpad with new Dell not recognised
Hi LKML,
Thanks to Vojtech for some advice, I finally got something happening
with this. Turns out I had to add support for a new model in alps.c,
the attached file does this successfully for my laptop. It'd be nice to
have others test it, but I am yet to find anyone else who has this same
laptop, with the same mouse issues I have.

With this patch, I now get a functioning touchpad, including side
scrolling, circle scrolling, corner taps etc. However, I did have to
ramp the configuration numbers up significantly from my old Thinkpad
with its synaptics touchpad. Minspeed is now 0.8 and maxspeed is 10.
Also the VertScrollDelta is 10. I don't know whether these numbers are
crazy high, or just normal for the Alps though.
