Hi Ed,

Your other patch to call input_unregister_device() looks good -- thanks!

I've never used a horizontal scroll wheel -- what are the common uses
for it?  Why should the acceleration be separate for the two directions
rather than using the same factor?  Why does the kernel need to emulate
this rather than having user-space implement the emulation?

(If the answers to the last two questions justify putting this feature
in the kernel, my only suggestions on the patch are style-related:
scroll_accel{x,y} should probably be spelled scroll_accel_{x,y}, and
there are missing spaces around the / operator when calculating stepx
and stepy.)
